    Full Text Available Objetivo: La analgesia preventiva consiste en la administración de fármacos para conseguir un estado analgésico previo al trauma quirúrgico que disminuya la respuesta sensitiva periférica y central al dolor, con la cual se intenta interrumpir el círculo inflamacióndolor-hiperalgesia-aumento del estímulo doloroso. Pregabalina es un neuromodulador utilizado en el tratamiento del dolor neuropático; varios trabajos indican que se puede administrar en la prevención del dolor postoperatorio. El objetivo de este trabajo fue realizar un estudio comparativo de dolor postoperatorio en pacientes intervenidos de hernia por cirugía abierta con colocación de malla, tratados con pregabalina o sin ella. Material y métodos: Se realizó un estudio prospectivo, aleatorizado, que incluyó a 140 pacientes intervenidos de hernia inguinal, crural o umbilical con malla, por cirugía abierta, con 112 varones y 28 mujeres. Grupo I: 70 de ellos fueron tratados con pregabalina 75 mg noche durante 3 días antes de la intervención y 75 mg noche durante 12 días después, incluido el día de la intervención. Grupo II: 70 sin pregabalina. No hubo diferencias entre ambos grupos en edad, que estaban comprendidos entre 18-79 años (edad media: 55,47 ± 13,38 años ni tampoco en el grado ASA: entre I-III. La evaluación del dolor se basó en la escala analógica verbal y consumo de pirazolonas. Los controles se realizaron después de 1, 6 y 12 meses de la intervención. Se registraron los efectos adversos, el número de horas de sueño y la mejoría o no en la calidad del sueño. El análisis estadístico se realizó con el test de Kolmogorov-Smirnov del programa Statgraphics. Se consideró significativa una p Objective: Preventive analgesia consists of administrating drugs to achieve an analgesic state that decreases the peripheral and central sensory response to pain prior to surgical injury; thus, the aim is to break the cycle of inflammation

    El alivio del dolor por medio de la acupuntura se desarrollo en la China moderna después de 1945 con la influencia inicial de la medicina occidental. Según la teoría tradicional, la acupuntura es eficaz sólo cuando las agujas producen el fenómeno “De Qi”, descrito como una sensación ligeramente dolorosa, relajante y si los dedos del acupuntor notan que las agujas son aspiradas por el punto tratado. En el Occidente diferentes estudios han demostrado que la acupuntura estimula fibras aferentes ...

Material y Método: El grupo de estudio lo componen 25 gestantes sanas, primigestas a término, con parto eutócico instaurado, que solicitan analgesia durante el trabajo de parto. Resultados: Se produce un alivio significativo del dolor desde la primera hora de tratamiento en todos los casos. La analgesia se mantiene hasta el final en el 80% de los casos. El 20% restante solicitó anestesia regional en el período expulsivo. Se produjo un grado de sedación de leve a moderado durante todo el estudio, que las pacientes valoraron positivamente. Solo en dos casos el grado de sedación fue moderado-severo, a pesar de lo cual las gestantes decidieron continuar en el estudio. No se registraron efectos adversos materno-fetales. Conclusiones: La analgesia del parto con Remifentanilo por vía intravenosa controlada por la paciente es un método efectivo y presenta un aceptable perfil de seguridad materno y fetal.Objective: To assess the analgesic efficacy of patient-controlled in-travenous analgesia with remifentanil and its potential side effects during labour. Method: We analyzed 25 healthy nulliparas at full term pregnancy, in established uncomplicated labour, who demanded pain relief. Results: All the patients experienced a significant pain relief during the first hour of treatment which was maintained on until delivery on 80%. The other 20% required additional regional anaesthesia at the end of second stage. The level of sedation was mild to moderate and treatment was well tolerated except for two, who presented heavy sedation. No maternal or neonatal side effects were registered. Conclusions: Patient-controlled intravenous analgesia with remifentanil is effective for labour pain relief and produces no major maternal and neonatal side effects.

    Full Text Available La Esclerosis Múltiple (EM, es una enfermedad del SNC siendo 2 veces más frecuente su aparición en mujeres, el 70% de ellas en edad fértil. Desde el punto de vista anestésico nos encontramos ante una enfermedad con elevada susceptibilidad neurológica que podría agravarse tanto por la propia cirugía, la técnica anestésica como por la medicación utilizada. Por otra parte se plantea como atender la demanda de analgesia para el trabajo de parto en mujeres con EM, que es el grupo de edad con mayor incidencia de la enfermedad. Presentamos el caso de una mujer de 37 años diagnosticada de esclerosis múltiples 3 años antes, forma recidivante, remitente. La paciente es ingresada en dilatación con 37 semanas de amenorrea, presentando una buena evolución del trabajo de parto y encontrándose el feto en situación longitudinal y presentación cefálica. Avisan al Servicio de Anestesia para valoración de la indicación de epidural para analgesia del parto. La gestante previamente había acudido a consulta de preanestesia donde se le había informado del riesgo beneficio de la técnica y en concreto en su caso, habiendo entendido perfectamente las posibles complicaciones derivadas de la misma y firmado el consentimiento informado. Nosotros hemos preferido utilizar una técnica locoregional, vía epidural considerando también el riesgo potencial de cesárea urgente, para evitar, dado el caso la realización de una técnica intraraquídea o una anestesia general, con las posibilidades de desencadenar un brote que tienen estas técnicas. Además de aportar confort a la paciente durante el trabajo de parto, proporcionar analgesia durante el mismo, disminuye por este motivo el estrés de la gestante pudiendo paralelamente evitar la aparición de un brote.Multiple sclerosis (MS is a disease of the central nervous system (CNS, and twice as prevalent in women, 70% of whom are of fertile age.

    2014-12-01

    Full Text Available Introducción: la analgesia epidural obstétrica continúa siendo el "gold-standard" para controlar el dolor durante el trabajo de parto, pero en determinadas ocasiones la técnica está contraindicada o la analgesia es incompleta. El remifentanilo es un opioide potente de rápida acción y vida media ultracorta, que se adapta perfectamente a la dinámica del parto. La coordinación entre el comienzo de las contracciones y la administración del fármaco mediante un dispositivo PCA hacen que esta técnica pueda ser considerada de elección para el alivio de dolor durante el parto y no solo como alternativa a la epidural. Objetivo: este estudio pretende valorar la eficacia y seguridad en el parto del remifentanilo administrado por vía intravenosa, así como la satisfacción materna de la analgesia recibida. Materiales y métodos: estudio descriptivo prospectivo basado en el análisis de la recogida de datos realizado por los investigadores durante el parto donde se recoge el dolor durante la dilatación y el expulsivo antes y después de la aplicación de la PCA de remifentanilo, así como las complicaciones y la incidencia de efectos secundarios. Paralelamente se realiza una encuesta de satisfacción materna de la técnica recibida y su vivencia personal. Resultados: se han recogido un total de 32 casos durante el periodo de estudio (6 meses. Todas las pacientes han presentado una reducción de dolor manifestado por una disminución del EVA respecto del dolor basal de 5,9 puntos en los primeros minutos, 4,6 puntos en completa y 3,4 en el expulsivo. No se han registrado complicaciones materno-fetales importantes derivadas de la técnica. La satisfacción materna ha sido alta, volviendo incluso a repetir la técnica en un 90 % de los casos. Conclusiones: la PCA de remifentanilo ha demostrado ser efectiva y segura como analgesia obstétrica. Es por ello que la PCA ha teniendo una amplia aceptación entre matronas, ginecólogos y anestesiólogos en

    INTRODUCTION: Acute abdominal pain is a very frequent cause of medical consultation. Early analgesia is not usually given to patients that present with it as their chief complaint, because of the many differential diagnoses that must be taken into consideration and also because of fear of the potential complications that may ensue if an early and accurate diagnosis is not made. Nowadays medical practice is evolving and it is pertinent to ask and answer whether it is still adequate to keep the...

    Full Text Available La analgesia multimodal que participa actualmente en todos los protocolos de analgesia postoperatoria también se utiliza por los especialistas en dolor crónico que manejan la combinación de fármacos como una rutina para optimizar la eficacia de la analgesia; la combinación de fármacos es una práctica bien conocida y muy extendida, gracias a su demostrada rentabilidad terapéutica, y habitualmente se utiliza tanto en anestesia como en analgesia. El concepto del balance adecuado entre efectividad y seguridad es primordial, y aunque la calidad del tratamiento aplicado se mide según el alivio conseguido, el confort se evalúa teniendo en cuenta la combinación entre eficacia analgésica y la ausencia o mínima presencia de efectos secundarios, siendo primordial en el tratamiento del paciente con dolor. En este sentido, parece claro que la búsqueda de las dosis mínimas eficaces de cada fármaco es una premisa necesaria para plantear la combinación de dosis idónea. La búsqueda de los fármacos que deben componer una combinación y las dosis a emplear debe ser fruto de la investigación, pero debe ser corroborada por la experiencia clínica, la opinión de los expertos y las evidencias publicadas. En este trabajo, se realiza una extensa revisión de la experiencia clínica existente con la combinación de ibuprofeno con codeína, haciendo un análisis de los antecedentes históricos que llevaron a su uso, los trabajos que permitieron demostrar su sinergia y compatibilidad farmacocinética y los trabajos pioneros de investigación clínica que permitieron concluir que la dosis fija idónea de esta combinación es la mezcla de 400 mg de ibuprofeno con 30 mg de codeína. Es difícil sacar conclusiones acerca de la efectividad analgésica de los diferentes antiinflamatorios no esteroideos, pero no cabe duda que según los datos acumulados hasta la actualidad, el ibuprofeno se sitúa entre los más efectivos y es una buena opción para

    This paper will discuss the concepts of pre-emptive and preventive analgesia in acute and persistent postsurgical pain, based on the most recent experimental and clinical literature, with a special focus on injury-induced central sensitization and the development from acute to chronic pain. Recent...... findings: The nature of central sensitization during acute and chronic postsurgical pain share common features, and there may be interactions between acute and persistent postoperative pain. The term ‘pre-emptive analgesia’ should be abandoned and replaced by the term ‘preventive analgesia’. Recent studies...... of preventive analgesia for persistent postoperative pain are promising. However, clinicians must be aware of the demands for improved design of their clinical studies in order to get more conclusive answers regarding the different avenues for intervention.

La flagrancia es una excepción a esa orden de autoridad judicial competente para limitar la libertad personal, pero en el artículo 28, inciso segundo de la Constitución Política, existe la llamada Detención Preventiva Administrativa, cuyos lineamientos para su aplicación, fueron trazados por la Corte Constitucional, sin que se requiriera orden de autoridad judicial competente para privar de la libertad personal a una persona. Posteriormente, con la vigencia del Sistema Penal de corte Acusatorio, dicha figura fue cuestionada y se tornó dudosa su aplicación conforme los lineamientos trazados por la Corte Constitucional.Posteriormente, la Corte Constitucional retoma el tema de la Detención Preventiva Administrativa, retira del ordenamiento jurídico la interpretación anterior y concluye que la Detención preventiva Administrativa procede siempre que exista orden de captura proferida por una autoridad judicial competente. Posteriormente, la Corte Suprema de Justicia, Sala de Casación Penal, en algunas decisiones de habeas corpus, parece revivir la figura de la Detención Preventiva Administrativa.

O objetivo deste estudo foi comparar o bloqueio dos nervos supraescapular e axilar nas cirurgias artroscópicas de ombro com a abordagem interescalênica do plexo braquial. MÉTODO: Sessenta e oito pacientes foram alocados em dois grupos de 34, de acordo com a técnica utilizada: grupo interescalênico (GI e grupo seletivo (GS, sendo ambas as abordagens realizadas com neuroestimulador. No GI, após resposta motora adequada foram injetados 30 mL de levopubivacaína em excesso enantiomérico de 50% a 0,33% com adrenalina 1:200.000. No GS, após resposta motora do nervo supraescapular e axilar, foram injetados 15 mL da mesma substância em cada nervo. Em seguida, realizada anestesia geral. Variáveis avaliadas: tempo para realização dos bloqueios, analgesia, consumo de opioide, bloqueio motor, estabilidade cardiocirculatória, satisfação e aceitabilidade pelo paciente. RESULTADOS: Tempo para execução do bloqueio interescalênico foi significativamente menor que para realização do bloqueio seletivo. Analgesia foi significativamente maior no pós-operatório imediato no GI e no pós-operatório tardio no GS. Consumo de morfina foi significativamente maior na primeira hora no GS. Bloqueio motor foi significativamente menor no GS. Estabilidade cardiocirculatória, satisfação e aceitabilidade da técnica pelo paciente não diferiram entre os grupos. Ocorreu uma falha no GI e duas no GS. CONCLUSÕES: Ambas as técnicas são seguras, eficazes com mesmo grau de satisfação e aceitabilidade. O bloqueio seletivo de ambos os nervos apresentou analgesia satisfatória, com a vantagem de proporcionar bloqueio motor restrito ao ombro.JUSTIFICATIVA Y OBJETIVOS: Las cirugías artroscópicas del hombro cursan con un intenso dolor postoperatorio.

    Full Text Available Introducción: El bloqueo del nervio ciático en la fosa poplítea proporciona una adecuada y prolongada analgesia postoperatoria en la cirugía del pie y tobillo. La principal ventaja del abordaje lateral es que no es preciso modificar la posición de decúbito supino del paciente para la realización de la técnica, mientras que en el abordaje posterior el paciente ha de colocarse en decúbito prono, lo cual puede resultar difícil e incluso desaconsejable en determinadas situaciones: estados avanzados de gestación, inestabilidad hemodinámica y ventilación mecánica. Material y método: Se incluyeron pacientes valorados con riesgo anestésico ASA I-II, programados para cirugía ortopédica-traumatológica del pie o tobillo. Se realizó un bloqueo del nervio ciático en la fosa poplítea mediante abordaje lateral según la técnica descrita por Vloka J.D y Hadzic A, empleándose una aguja para neuroestimulación, biselada de calibre 22G x 80 mm. Se consideró como respuesta motora adecuada cualquier movimiento del pie o dedos a intensidad inferior a 0,4 mA y superior a 0,1 mA. La observación de una respuesta motora a intensidad de estimulación de 0,1 mA se consideró como localización intraneural de la aguja. Se inyectaron 40 mL de ropivacaína 0,5%. Las principales variables que se registraron a las 8, 16 y 24 horas tras la realización del bloqueo fueron el dolor en reposo y en movimiento según la escala visual analógica (EVA de 0-10 y el grado de satisfacción. Resultados: Se incluyeron 21 pacientes ASA I-II. El dolor medio en reposo fue valorado como de intensidad 1 en las primeras 8 horas y de intensidad 3 a las 16 h y 24 h tras la realización del bloqueo. El dolor medio con el movimiento articular fue valorado como de intensidad 2 a las 8 h y de intensidad 4 a las 16 h y 24 h tras el bloqueo.

MÉTODO: Treinta y siete pacientes fueron ubicados aleatoriamente en dos grupos según el anestésico local utilizado en el bloqueo: Grupo B - bupivacaína a 0,5% con epinefrina 1:200.000 o Grupo R - ropivacaína a 0,5%. Durante el período postoperatorio, los puntajes de dolor y el consumo de morfina en la analgesia controlada por el paciente, fueron comparados entre los grupos. El sangramiento durante la operación y la incidencia de efectos adversos y de complicaciones también fueron comparados. RESULTADOS: Pese a que los puntajes de dolor hayan sido menores en el Grupo R 8 horas, 12 horas y 24 horas después del bloqueo, esas diferencias no fueron clínicamente significativas. La regresión lineal múltiple no identificó el anestésico local como una variable independiente. No hubo diferencia en el consumo de morfina, en el sangramiento intraoperatorio y en la incidencia de complicaciones y efectos adversos entre los dos grupos.

    The effect of ethanol (ET) on nociceptive sensitivity was evaluated using a new tail deflection response (TDR) method. The IP injection of ET (0.5 - 1.5 g/kg) produced raid dose-dependent analgesia. Near maximal effect (97% decrease in TDR) was produced with the 1.5 g/kg dose of ET ten minutes after injection. At ninety minutes post-injection there was still significant analgesia. Depression of ET-induced nociceptive sensitivity was partially reversed by a 1 mg/kg dose of naloxone. On the other hand, morphine (0.5 or 5.0 mg/kg IP) did not modify ET-induced analgesia, while 3.0 minutes of cold water swim (known to produce non-opioid mediated analgesia) potentiated ET-induced analgesic effect. The 0.5 g/kg dose of ET by itself did not depress motor activity in an open field test, but prevented partially the depression in motor activity produced by cold water swim (CWS). Thus, the potentiation by ET of the depression of the TDR produced by CWS cannot be ascribed to the depressant effects of ET on motor activity. 21 references, 4 figures, 1 table.

    Full Text Available Background: Epidural analgesia is claimed to result in prolonged labor. Previous studies have assessed epidural analgesia vs systemic opioids rather than to parturients receiving no analgesia. This study aimed to evaluate the effect of epidural analgesia on labor duration compared with parturients devoid of analgesia. Methods: One hundred sixty nulliparous women in spontaneous labor at full term with a singleton vertex presentation were assigned to the study. Parturients who request epidural analgesia were allocated in the epidural group, whereas those not enthusiastic to labor analgesia were allocated in the control group. Epidural analgesia was provided with 20 mL bolus 0.5% epidural lidocaine plus fentanyl and maintained at 10 mL for 1 h. Duration of the first and second stages of labor, number of parturients receiving oxytocin, maximal oxytocin dose required for each parturient, numbers of instrumental vaginal, vacuum-assisted, and cesarean deliveries and neonatal Apgar score were recorded. Results: There was no statistical difference in the duration of the active-first and the second stages of labor, instrumental delivery, vacuum-assisted or cesarean delivery rates, the number of newborns with 1-min and 5-min Apgar scores less than 7 between both groups and number of parturients receiving oxytocin, however, the maximal oxytocin dose was significantly higher in the epidural group. Conclusion: Epidural analgesia by lidocaine (0.5% and fentanyl does not prolong labor compared with parturients without analgesia; however, significant oxytocin augmentation is required during the epidural analgesia to keep up the aforementioned average labor duration.

A analgesia adjuvante complementar é habitualmente utilizada nos tratamentos fisiátricos, ortopédicos, reumatológicos, obstétricos e com acupuntura. A analgesia alternativa complementar pode potencializar os métodos analgésicos convencionais, a exposição à luz do sol matutino, luz e cores sob luz artificial, o tempo (T - anestésicos gerais mais potentes à noite, opióides de manhã e anestésicos locais à tarde, dieta, bom humor e riso, espiritualidade, religião, meditação, musicoterapia, hipnose e efeito placebo. CONCLUSÕES: Se a dor aguda é um mecanismo de defesa, a dor crônica é um estado patológico desagradável relacionado com a depressão endógena e a uma baixa qualidade de vida. É importante estabelecer relações interdisciplinares entre a Medicina adjuvante e alternativa nas terapias analgésicas e antiinflamatórias clássicas.

    Full Text Available El objetivo de esta revisión es una puesta al día en la etiología, diagnóstico, profilaxis y tratamiento de la meningitis tras anestesia y analgesia espinales. Aunque es una complicación mayor de esta técnica y su incidencia es baja, cada vez son más frecuentes los casos publicados en la literatura médica. Según su etiología se les clasifica en meningitis sépticas, víricas y asépticas. Las meningitis sépticas son las más frecuentes, y en su etiología cada vez juega un papel más destacado como agente implicado el estreptococo salivarius. Como meningitis asépticas se clasifican aquellas en las que el cultivo de líquido cefalorraquídeo es negativo, con un periodo de latencia de síntomas inferior a seis horas, que pueden cursar con eosinofilia en el líquido cefalorraquídeo y unos niveles cercanos a la normalidad en la glucorraquia. Suelen tener buena respuesta y evolución con tratamiento antibiótico con vancomicina y cefalosporinas de tercera generación. Como profilaxis incidir en las medidas de asepsia, sobre todo en el uso de mascarilla facial para realizar la técnica, como práctica para disminuir la incidencia de gérmenes cuyo origen está en la cavidad oral y orofaringe. Asimismo podrían reducir la incidencia de meningitis las medidas de asepsia tales como el lavado de manos, uso de guantes y asepsia de la piel. La diferenciación entre meningitis séptica y aséptica se hará con mayor seguridad cuando se estandaricen las técnicas para detectar genoma bacteriano en el líquido cefalorraquídeo; actualmente se etiquetan como meningitis asépticas aquellas en las que el cultivo de líquido cefalorraquídeo es negativo y cuya tinción de Gram es negativa. Pese a que el pronóstico y evolución en rasgos generales de las meningitis tras anestesia y analgesia espinal es bueno, en comparación con las meningitis adquiridas en la comunidad, por la escasa virulencia de las bacterias implicadas (Estreptococo salivarius

Essas atividades têm sido fortalecidas atualmente por meio de ações programáticas de saúde e manejo das doenças crônicas não transmissíveis. Esse contexto reforça a importância de se entenderem as bases da prevenção, discutidas no livro Estratégias da Medicina Preventiva de Geoffrey Rose.1 Rose classifica a prevenção de doenças em duas abordagens: a estratégia de alto risco (EAR e a estratégia de amplitude populacional (EAP. A primeira refere-se ao processo de separação entre os indivíduos de alto risco e os demais. A segunda visa abranger a população como um todo. A estratégia de alto risco parte de uma lógica binária de processo decisório que na medicina é denominada diagnose, ou seja, a pessoa tem ou não a condição a ser investigada. Em caso positivo, alguma intervenção lhe é oferecida; em caso negativo, ‘deixa-se a pessoa em paz’. A EAR é muito atrativa e, tradicionalmente, mais lógica e adequada: primeiro, porque faz sentido tanto aos profissionais como aos pacientes, visto que ambos entendem mais facilmente o porquê da intervenção; segundo, por ser custo-efetiva, pois os recursos são direcionados àqueles que mais precisam; finalmente, porque se encaixa mais no cotidiano dos serviços, que geralmente operam na lógica do modelo individual do cuidado às doenças.Existem, no entanto, algumas desvantagens desse tipo de intervenção: (1 tende-se a medicalizar a prevenção; (2 há que se manter o programa indefinidamente, pois não se intervém no problema de base; e (3 é difícil para aquele que recebe a intervenção quantificar seu real benefício, visto que se opera no campo da probabilidade (NNT: número necessário para tratar durante certo tempo para que uma pessoa se beneficie. Qual pessoa irá se beneficiar? Não sabemos. Porém, o

A prospective and consecutive series of 1,316 patients undergoing surgery from September 1999 to April 2003 and using opioids post surgery were studied. From the 1,136 patients, 594 did not use urinary catheters pre-surgery. From these 594 patients, 128 (22% suffered post operative urinary retention. Urinary retention was significantly related to the use of continuous epidural analgesia (p=0.009. About 69% of patients experiencing urinary retention post surgery returned to spontaneous micturition following a single catheterization. The incidence found of urinary retention was similar to the literature, more frequent in men who received continuous epidural analgesia. The findings suggest orientation and careful nursing team observation of post operative micturition, emphasizing the intermittent aseptically catheterization for urinary retention in order to prevent potential complications of the urinary tract.Los objetivos de este estudio fueron determinar la incidencia de retención urinaria post-operatoria en pacientes que se encontraban en uso de analgésicos opioides, así como describir el método utilizado en el vaciado vesical.

    Full Text Available La obesidad es un problema global de salud en continuo aumento en el mundo desarrollado. Dado que la incidencia de la obesidad es mayor en mujeres que en hombres, los anestesiólogos con especial dedicación a la obstetricia, tendrán mayor oportunidad de enfrentarse a este tipo de pacientes. Nuestro objetivo es determinar la dificultad en la realización de la técnica epidural para analgesia de parto y analizar la incidencia de complicaciones ocurridas durante la punción en las gestantes obesas, así como evaluar la eficacia de la analgesia epidural en este grupo de pacientes en un estudio observacional retrospectivo de todos los bloqueos epidurales para analgesia de parto realizados en un hospital universitario de nivel 4 durante un periodo de cuatro años. Se ha estudiado un total de 13616 pacientes, clasificándolas según el índice de masa corporal en Kg./m² (IMC. En las pacientes no obesas (IMCObesity is an increasing global health problem in Developer countries.

    1993-09-01

    The spectrum of perioperative pain treatment is discussed in the present review. The analgesic efficacy of various drugs and the dosage methods of administration and side effects reported for them in such reference works as the practical guide on the management of acute pain recently published by the International Association for the Study of Pain (IASP) are described. Effective postoperative analgesia can diminish stress reactions following surgery. Recovery and physical mobilization are improved as the result of adequate treatment. Results obtained in recent studies have demonstrated that primary adaptive hyperalgesia in the peripheral nociceptive area may develop into secondary maladaptive hypersensibility with a high degree of nociceptive excitability and pain. Chronic pain can develop following acute alterations. Increasing nociceptive activity of primary afferents induces alterations in the dorsal horn of the spinal cord. These alterations imply an increase in the excitability of nociceptive neurons, which has been described as neuronal plasticity. Clinical results have demonstrated prevention or delay of acute postoperative pain after injection of local anaesthetics, analgesic premedication or epidural injection of opioids just before the start of surgery. Continuous perioperative spinal analgesia has contributed significantly to the prevention of phantom limb pain in patients undergoing amputation of extremities. The development of pain memory may be prevented as a result of effective acute pain treatment. Several changes to the terminology of acute pain treatment for animal and clinical studies have recently been proposed, including such new terms as preemptive analgesia and pain prevention, which indicate new strategies in the treatment of postoperative pain. The concept of balanced analgesia refers to a strategy for the improvement of analgesic efficacy as a result of a combination of drugs with different local actions on nociception. The combination of

    Full Text Available La analgesia postoperatoria es uno de los componentes básicos en la recuperación funcional tras una intervención quirúrgica. No obstante, es difícil aislar los efectos de la analgesia postoperatoria de otros aspectos relacionados con la técnica quirúrgica, la práctica clínica, el tipo de seguimiento analgésico o los factores organizativos del equipo quirúrgico. La introducción de la laparoscopia, la toracoscopia y las técnicas quirúrgicas mínimamente invasivas está modificando los protocolos analgésicos clásicos en la cirugía compleja. La analgesia intravenosa controlada por el paciente e incluso los opioides por vía oral están desplazando a la analgesia epidural en este tipo de técnicas. La evaluación del riesgo/beneficio para la selección de cada tipo de analgesia postoperatoria dependerá de la severidad del dolor dinámico y de los potenciales efectos secundarios de las técnicas y los fármacos analgésicos. Es difícil demostrar el impacto de la analgesia postoperatoria en grandes resultados quirúrgicos como la mortalidad, la morbilidad o la estancia media, que dependen de factores múltiples y heterogéneos. El efecto del tipo de analgesia en el proceso quirúrgico debería investigarse sobre otros resultados orientados al paciente, como la calidad analgésica, los efectos adversos o el bienestar postoperatorio. Otras áreas en las que se plantea el posible impacto de la analgesia postoperatoria son la recurrencia oncológica y el dolor crónico postoperatorio.

    2012-02-03

    Timely management of pain in paediatric patients in the Emergency Department (ED) is a well-accepted performance indicator. We describe an audit of the provision of analgesia for children in an Irish ED and the introduction of a nurse-initiated analgesia protocol in an effort to improve performance. 95 children aged 1-16 presenting consecutively to the ED were included and time from triage to analgesia, and the rate of analgesia provision, were recorded. The results were circulated and a nurse initiated analgesia protocol was introduced. An audit including 145 patients followed this. 55.6% of patients with major fractures received analgesia after a median time of 54 minutes, which improved to 61.1% (p = 0.735) after 7 minutes (p = 0.004). Pain score documentation was very poor throughout, improving only slightly from 0% to 19.3%. No child had a documented pain score, which slightly improved to 19.3%. We recommend other Irish EDs to audit their provision of analgesia for children.

El uso de los servicios de salud es una conducta dinámica de la población. Para que la gente utilice estas acciones de prevención es necesario que se reduzcan barreras de acceso. Así, el objetivo del estudio fue determinar la utilización de los servicios de detección de diabetes mellitus, hipertensión arterial, cáncer cérvicouterino y mamario y aplicación del toxoide tetánico diftérico. Métodos: El tamaño de la muestra fue de 254 personas de 25 años y más, que habitaban en Monterrey y su zona metropolitana. En el uso de acciones preventivas se consideró a las personas que las habían usado el año anterior. El análisis consistió en estadística descriptiva y análisis bivariado. Resultados: Más del 60% de la población correspondió al sexo femenino, la edad promedio fue de 42,3 años±14 años y tres cuartas partes de la población contó con seguridad social. Un 37% mencionó haberse realizado la detección de diabetes y un 44,5% de hipertensión, mientras que le aplicaron el toxoide tetánico diftérico a un 31,1%. En las detecciones propias de la mujer, a un 34,3% de la población femenina le practicaron la correspondiente a cáncer cérvicouterino en tanto que a un 29,5%, la de cáncer mamario. No hubo relación entre uso de acciones con antecedentes familiares y percepción de importancia de la detección. Conclusiones: El uso de las acciones preventivas está por debajo de algunos estándares internacionales.

However its uptake by pregnant women is limited compared to other western countries, partly as a result of non-availability due to logistic problems. Remifentanil, a synthetic opioid, is very suitable for patient controlled analgesia. Recent studies show that epidural analgesia is superior to remifentanil patient controlled analgesia in terms of pain intensity score; however there was no difference in satisfaction with pain relief between both treatments. Methods/design The proposed study is a multicentre randomized controlled study that assesses the cost-effectiveness of remifentanil patient controlled analgesia compared to epidural analgesia. We hypothesize that remifentanil patient controlled analgesia is as effective in improving pain appreciation scores as epidural analgesia, with lower costs and easier achievement of 24 hours availability of pain relief for women in labour and efficient pain relief for those with a contraindication for epidural analgesia. Eligible women will be informed about the study and randomized before active labour has started. Women will be randomly allocated to a strategy based on epidural analgesia or on remifentanil patient controlled analgesia when they request pain relief during labour. Primary outcome is the pain appreciation score, i.e. satisfaction with pain relief. Secondary outcome parameters are costs, patient satisfaction, pain scores (pain-intensity, mode of delivery and maternal and neonatal side effects. The economic analysis will be performed from a short-term healthcare perspective. For both strategies the cost of perinatal care for mother and child, starting at the onset of labour and ending ten days after delivery, will be registered and compared. Discussion This study, considering cost

    Background Connexin 43 (Cx43) is one of the major components of human keratinocyte gap junctions. To study whether gap junctional intercellular communication participates in the transfer of acupoint signals and acupuncture analgesia, the expression of Cx43 was studied in Zusanli (ST36) acupoints compared with control non-acupoint regions in rats after acupuncture. In addition, Cx43 heterozygous gene knockout mice were used to further explore the relationship between Cx43 and acupuncture analgesia. Methods The expression of Cx43 was detected by immunohistochemistry, immunoblotting, and RT-PCR for the Cx43 protein and mRNA. The influence of the Cx43 gene knockout on acupuncture analgesia was measured by a hot plate and observing the writhing response on Cx43 heterozygous gene knockout mice. Results Immunohistochemistry showed abundant Cx43 expression in some cells in the skin and subcutaneous tissue of rat ST36 acupoints. The mRNA and protein levels of Cx43 in acupoints were significantly higher than those in the control points in the non-acupuncture group, and even more so after acupuncture. The hot plate and writhing response experiments showed that partial knockout of the Cx43 gene decreased acupuncture analgesia. Conclusion Cx43 expression and acupuncture analgesia showed a positive correlation.

    Although non-suicidal self-injury (NSSI) involves self-inflicted physical harm, many self-injurers report feeling little or no pain during the act. Here we test: (1) whether the pain analgesia effects observed among adult self-injurers are also present among adolescents, and (2) three potential explanatory models proposing that habituation, dissociation, and/or self-criticism help explain the association between NSSI and pain analgesia among adolescents. Participants were 79 adolescents (12-19 years) recruited from the community who took part in a laboratory-based pain study. Results revealed that adolescent self-injurers have a higher pain threshold and greater pain endurance than non-injurers. Statistical mediation models revealed that the habituation and dissociation models were not supported; however, a self-critical style does mediate the association between NSSI and pain analgesia. The present findings extend earlier work by highlighting that a self-critical style may help to explain why self-injurers exhibit pain analgesia. Specifically, the tendency to experience self-critical thoughts in response to stressful events may represent a third variable that increases the likelihood of both NSSI and pain analgesia. Prospective experimental studies are needed to replicate and tease apart the direction of these associations, and may provide valuable leads in the development of effective treatments for this dangerous behavior problem.

    Although epidural analgesia is routinely used in many institutions for patients undergoing hepatic resection, there are unresolved issues regarding its safety and efficacy in this setting. We performed a review of papers published in the area of anaesthesia and analgesia for liver resection surgery and selected four areas of current controversy for the focus of this review: the safety of epidural catheters with respect to postoperative coagulopathy, a common feature of this type of surgery; analgesic efficacy; associated peri-operative fluid administration; and the role of epidural analgesia in enhanced recovery protocols. In all four areas, issues are raised that question whether epidural anaesthesia is always the best choice for these patients. Unfortunately, the evidence available is insufficient to provide definitive answers, and it is clear that there are a number of areas of controversy that would benefit from high-quality clinical trials.

    Significant potentiation of morphine (5 mg kg-1 s.c. or 1 mg kg-1 i.v.) analgesia (tail-withdrawal reflex at 55 degrees C) was observed in caffeine-treated (100 mg kg-1 i.p.) rats as compared to the control group and lower doses of caffeine (2mg kg-1 i.p.) did not show this effect. Potentiated analgesia was reversed by naloxone. Pharmacokinetic or dispositional factors appear to be involved in part in this potentiation. PMID:4005485

    Epidural anaesthesia is a widely used and accepted technique for perioperative analgesia in different kinds of surgery. Apart from analgetic effect and due to wide positve effects on patients outcome epidural analgesia is often used with general anaesthesia. It represents a reliable and reversible neural deafferentation technique that effectively contributes to a reduction of the surgical stress response with subsequent positive effects on cardiopulmonary, gastrointestinal, and immune function. Animal studies suggest that the use of epidural anaesthesia may be beneficial for cancer surgery because of less tumour recurrence. Further, a benefit is expected in patient's mortality. This article summarizes and critically discusses the current knowledge on the effects of epidural anaesthesia on pain management, cardiopulmonary as well as gastrointestinal functions and patient's outcome.

    We consider that the present state of postoperative analgesia is unsatisfactory because drugs are given intermittently and usually only at the patients' request and with nurses' acquiescence. A procedure for routine continuous pethidine infusion, suitable for administration and control by the nursing staff is described. The results of a trial on patients after major surgery are summarised. We believe the procedure to be more efficient and effective than those presently in use.

    Full Text Available Intrathecal analgesia is an interventional form of pain relief with definite advantages and multiple complications. Administration of intrathecal analgesia needs a good resource setting and expertise. Early complications of intrathecal analgesia can be very distressing and managing these complications will need a high degree of knowledge, technical expertise and level of experience. Pain control alone cannot be the marker of quality in palliative care. A holistic approach may need to be employed that is more person and family oriented.

    Obstetric anesthesia has made significant progress over the last 50 years. It is one of the major subspecialties in anesthesia in US. Society for Obstetric Anesthesia and Perinatology (SOAP) was founded in 1968. According to its SCORE project on the practice of obstetric anesthesia, 82.4% of all parturients received some form of anesthesia for cesarean section or labor analgesia. Epidural analgesia was the most common form of labor analgesia (65%), followed by CSEA. This high percentage of anesthesia care for parturients mandates the presence of obstetric anesthesiologists at labor and delivery suites in major hospitals in US. The Japanese Society of Obstetrics and Anesthesia, formerly "Mutsu-bunben Kenkyukai", now called "Bunben to Masui Kenkyukai", was founded in Japan at about the same time as SOAP. Despite its long history, obstetric anesthesia is yet to be a major subspecialty in Japan. It is encouraging, however, that the number of attendants in obstetric anesthesia sessions in JSA seems increasing. SOAP has played an important role in the education and progress of obstetric anesthesia in US. I hope that the joint symposium of SOAP, Bunben to Masui Kenkyukai, and JSA at 39th SOAP annual meeting will facilitate the progress of obstetric anesthesia in Japan. PMID:17877044

    Full Text Available The placebo effect is a neurobiological and psychophysiological process known to influence perceived pain relief. Optimization of placebo analgesia may contribute to the clinical efficacy and effectiveness of medication for acute and chronic pain management. We know that the placebo effect operates through two main mechanisms, expectations and learning, which is also influenced by sleep. Moreover, a recent study suggested that rapid eye movement (REM sleep is associated with modulation of expectation-mediated placebo analgesia. We examined placebo analgesia following pharmacological REM sleep deprivation and we tested the hypothesis that relief expectations and placebo analgesia would be improved by experimental REM sleep deprivation in healthy volunteers. Following an adaptive night in a sleep laboratory, 26 healthy volunteers underwent classical experimental placebo analgesic conditioning in the evening combined with pharmacological REM sleep deprivation (clonidine: 13 volunteers or inert control pill: 13 volunteers. Medication was administered in a double-blind manner at bedtime, and placebo analgesia was tested in the morning. Results revealed that 1 placebo analgesia improved with REM sleep deprivation; 2 pain relief expectations did not differ between REM sleep deprivation and control groups; and 3 REM sleep moderated the relationship between pain relief expectations and placebo analgesia. These results support the putative role of REM sleep in modulating placebo analgesia. The mechanisms involved in these improvements in placebo analgesia and pain relief following selective REM sleep deprivation should be further investigated.

    Full Text Available Background: Epidural analgesia is the most effective analgesics used during childbirth but is not without its problems.In the Hospital San Juan de la Cruz of Ubeda from November 2011 we have detected 3 cases of newborn infants with signs of respiratory depression. Appeared in them: normal cardiotocographic records during childbirth, use of epidural associated with fentanyl, termination by vacuum and elevated temperature in one case.ObjectivesKnow if the neonatal adaptation to extrauterine life may be influenced by the use of epidural analgesia in childbirth. Review what role can have the rise in maternal temperature and the use of epidural fentanyl with the appearance of newborn respiratory distress.MethodsLiterature Review conducted in February of 2012 in Pubmed and the Cochrane Library, using the key words: childbirth, epidural analgesia, neonatal respiratory depression.ResultsOn the respiratory depression associated with fentanyl, a Cochrane review found indicating that newborns of mothers with an epidural, had a lower pH and were less need for administration of naloxone.On PubMed we find a review study that indicates that the respiratory depression caused by the administration of opioids via neuroaxial is rare, placing it below 1 per 1000, and a clinical case that concluded that doses of fentanyl exceeding 300 µg (approx. 5 µg/kg for 4 hours previous to childbirth, have a high risk of neonatal respiratory depression at birth.The same Cochrane review indicates that the women with epidural analgesia had increased risk of maternal fever of at least 38 ° C and a recent cohort study relates this increase in temperature with a greater likelihood of neonatal adverse events (from 37.5 ° C.ConclusionsThe studies found considered safe epidurals to the neonate and the mother, except when certain conditions are met.

    2012-05-01

    In the nineties, spinal analgesia has been described as an useful means to control pain in advanced cancer patients. The aim of this review was to update this information with a systematic analysis of studies performed in the last 10 years. 27 papers pertinent with the topic selected for review were collected according to selection criteria. Few studies added further information on spinal analgesia in last decade. Despite a lack of a clinical evidence, spinal analgesia with a combination of opioids, principally morphine, and local anesthetics may allow to achieve analgesia in patients who had been intensively treated unsuccessfully with different trials of opioids. Some adjuvant drugs such as clonidine, ketamine, betamethasone, meperidine, and ziconotide may be promising agents, but several problems have to be solved before they can be used in the daily practice. In complex pain situations, spinal analgesia should not be negated to cancer patients, and oncologists should address this group of patients to other specialists. PMID:21684173

    Epidural analgesia has become increasingly popular as a form of labour analgesia in Ireland. However obtaining true inform consent has always been difficult. Our study recruited 100 parturients who had undergone epidural analgesia for labour, aimed to determine the information they received prior to regional analgesia, and to ascertain their preferences regarding informed consent. Only 65 (65%) of patients planned to have an epidural. Knowledge of potential complications was variable and inaccurate, with less than 30 (30%) of women aware of the most common complications. Most women 79 (79%) believed that discomfort during labour affected their ability to provide informed consent, and believe consent should be taken prior to onset of labour (96, 96%). The results of this study helps define the standards of consent Irish patients expect for epidural analgesia during labour.

    Since the introduction of chloroform for labour analgesia in 1847, different methods and medications have been used to relieve the pain of labour. The use of heavy sedative medication in the early 1900s was encouraged by enthusiastic doctors and by women empowered by the women's suffrage movement in America. Nitrous oxide by inhalation has been used in Australia since the 1950s and improved methods of administration have made this method of analgesia safe and practical. Caudal epidural analgesia and lumbar epidural analgesia were first made popular in America and by the 1970s these techniques were more widely available in Australia. In 1847, physicians and the public were unsure whether relieving labour pains was the 'right' thing to do. However, many medical and social changes have occurred thanks to the clinical connection between Australia and the United Kingdom and those first settlers to land on Australian shores. Thanks to this historical connection, in today's Australia there is no question that women should use analgesia as a pain relief if they wish. Currently, the majority of women worldwide use some form of analgesia during labour and different methods are widely available. This paper discusses the four milestones of the development of obstetric analgesia and how they were introduced into patient care in Australia. PMID:26126071

    Full Text Available We conducted a study to compare the efficacy and safety of Patient Controlled Epidural Analgesia (PCEA with that of Continuous Infusion of Epidural Analgesia (CIEA for maintenance of labour analgesia and evaluated the quality of analgesia and obstetric and safety outcomes. METHODS The study was a hospital-based prospective, randomised control trial on 80 parturients who had a normal antenatal period. Each parturient received 500-1000 mL lactated ringer solution Intravenously (IV prior to initiating epidural blockade. Epidural catheter placement was performed in a standard manner and all patients received an initial dose of 8-10 mL bupivacaine 0.25%. Parturients self-administered 0.125% bupivacaine with fentanyl 2.5 µg/mL using PCA pumps programmed as follows: 4 mL bolus with a 20 mins Lockout Interval (LI. Group B received CIEA of 8 mL 0.125% bupivacaine with fentanyl 2.5/mL. Hourly assessments included: VAS scores for pain and satisfaction, sensory and motor block, analgesic supplements, bupivacaine and fentanyl consumption. RESULTS Data from 80 patients showed no differences among groups in pain relief. Maternal satisfaction was greater in PCEA group. Anaesthetic interventions by way of supplemental doses of Bupivacaine and Fentanyl in the PCEA group were minimal (4 and 2 vs 25 and 12 P <0.001 compared to CEI group. PCEA group received less local anaesthetic (5.2 vs 9.4 p <0.001 and few patients in PCEA group had motor weakness compared to CEI group (6 vs 17 p <0.05. Both methods were safe for mother and newborn. CONCLUSION Patients who received PCEA required less anaesthetic interventions, required lower doses of local anaesthetic, fentanyl and have less motor weakness than those who received CEI.

    2013-01-01

    Full Text Available Background: The aim of preemptive analgesia is to reduce central sensitization that arises from noxious inputs across the entire perioperative period. N-methyl d-aspartate receptor antagonists have the potential for attenuating central sensitization and preventing central neuroplasticity. Materials and Methods: Patients undergoing laparoscopic cholecystectomy were randomized into four groups of 20 patients each, who were administered the study drug intravenously 30 min before incision. Groups A, B, and C received ketamine in a dose of 1.00, 0.75 and 0.50 mg/kg, respectively, whereas group D received isotonic saline. Anesthetic and surgical techniques were standardized. Postoperatively, the degree of pain at rest, movement, and deep breathing using visual analogue scale, time of request for first analgesic, total opioid consumption, and postoperative nausea and vomiting were recorded in postanesthesia care unit for 24 h. Results: Pain scores were highest in Group D at 0 h. Groups A, B, and C had significantly decreased postoperative pain scores at 0, 0.5, 3, 4, 5, 6, and 12 h. Postoperative analgesic consumption was significantly less in groups A, B, and C as compared with group D. There was no significant difference in the pain scores among groups A, B, and C. Group A had a significantly higher heart rate and blood pressure than groups B and C at 0 and 0.5 h along with 10% incidence of hallucinations. Conclusion: Preemptive ketamine has a definitive role in reducing postoperative pain and analgesic requirement in patients undergoing laparoscopic cholecystectomy. The lower dose of 0.5 mg/kg being devoid of any adverse effects and hemodynamic changes is an optimal dose for preemptive analgesia in patients undergoing laparoscopic cholecystectomy.

    >Fundamento: El dolor posoperatorio constituye un problema muy difundido y constante en los cuidados del paciente quirúrgico. La lucha por encontrar nuevas terapéuticas para aliviar el dolor ha llevado a la fabricación y uso de gran variedad de analgésicos que son administrados por diferentes vías. Se conocen bien los efectos de los narcóticos en el recién nacido y fue la preocupación al respecto lo que motivó el interés por el uso de esos fármacos por vía epidural e intratecal en la paciente obstétrica. Objetivo: Evaluar la factibilidad del uso de morfina liofilizada por vía peridural en la operación cesárea. Métodos : Estudio de serie de casos desarrollado durante el periodo comprendido entre febrero del 2001 a agosto del 2002 en la unidad quirúrgica del Servicio de Ginecoobstetricia del Hospital Universitario ¨Dr.Gustavo Aldereguía Lima¨ de Cienfuegos, que incluyó 120 pacientes sometidas a cesárea iterativa electiva. Se analizaron variables correspondientes a tensión arterial, frecuencia cardiaca, frecuencia respiratoria durante el preoperatorio, transoperatorio y posoperatorio, comienzo del efecto anestésico y duración de este, además se analizaron las complicaciones perioperatorias, la calidad de la analgesia posoperatoria y su repercusión en el recién nacido, medida mediante el puntaje de Apgar. El procesamiento estadístico se realizó utilizando el paquete estadístico Epi Info 6. Resultados : El comienzo del efecto anestésico y el tiempo de duración de la anestesia no se modificaron con el uso de la morfina liofilizada. Los parámetros vitales se mantuvieron con valores normales en la mayoría de las pacientes durante el preoperatorio, transoperatorio y posoperatorio. Las complicaciones que se presentaron fueron: prurito, retención urinaria, náuseas y vómitos. La calidad de la analgesia resultó satisfactoria en la mayoría de las pacientes.

    Despite widespread use of epidural analgesia during labor, no consensus has been reached among obstetric and anesthesia providers regarding its effects on breastfeeding. The purpose of this review was to examine the relationship between labor epidural analgesia and breastfeeding in the immediate postpartum period. PubMed, Cochrane Library, and Cumulative Index to Nursing and Allied Health Literature were searched for articles published in 1990 or thereafter, using the search term breastfeeding combined with epidural, labor epidural analgesia, labor analgesia, or epidural analgesia Of 117 articles, 23 described empirical studies specific to labor epidural analgesia and measured a breastfeeding outcome. Results were conflicting: 12 studies showed negative associations between epidural analgesia and breastfeeding success, 10 studies showed no effect, and 1 study showed a positive association. Most studies were observational. Of 3 randomized controlled studies, randomization methods were inadequate in 2 and not evaluable in 1. Other limitations were related to small sample size or inadequate study power; variation and lack of information regarding type and dosage of analgesia or use of other intrapartum interventions; differences in timing, definition, and method of assessing breastfeeding success; or failure to consider factors such as mothers' intention to breastfeed, social support, siblings, or the mother's need to return to work or school. It is also unclear to what extent results are mediated through effects on infant neurobehavior, maternal fever, oxytocin release, duration of labor, and need for instrumental delivery. Clinician awareness of factors affecting breastfeeding can help identify women at risk for breastfeeding difficulties in order to target support and resources effectively. PMID:27121239

Innumerables técnicas pueden ser utilizadas para la analgesia de parto. Este trabajo tuvo como objetivo comparar la técnica peridural continua con la combinada, ambas con el uso de bupivacaína a 0,25% en exceso enantiomérico 50% y fentanil como agentes. MÉTODO: Participaron del estudio 40 parturientes en trabajo de parto con dilatación cervical entre 4 y 5 cm que se repartieron en de los grupos iguales de forma aleatoria. El Grupo I recibió anestesia peridural continua. El Grupo II recibió anestesia combinada. Se evaluaron: medidas antropométricas, edad de embarazo, dilatación cervical, tiempo entre el bloqueo y la ausencia de dolor a través de la escala analógica visual, posibilidad de deambulación, tiempo entre el inicio de la analgesia y la dilatación cervical completa, duración del período expulsivo, parámetros hemodinámicos maternos y vital edad del recién nacido. Posibles complicaciones como depresión respiratoria, hipotensión arterial materna, prurito, náuseas y vómitos también fueron observados. Para la comparación de los promedios se utilizó el teste t de Student y para la paridad y tipo de parto se utilizó el teste del Qui-cuadrado. RESULTADOS: No hubo diferencia estadística significativa entre los de los grupos con relación al tiempo entre el inicio de la analgesia y la dilatación cervical completa, como también con relación al tiempo de la duración del período expulsivo, incidencia de cesárea relacionada con la analgesia, parámetros hemodinámicos maternos y vital edad del recién nacido.

    Full Text Available La analgesia epidural se ha convertido en una técnica rutinaria en el manejo perioperatorio de los pacientes quirúrgicos que se ha extendido fuera de los quirófanos y de las unidades de alta dependencia hacia las salas de hospitalización. La irrupción en este nuevo escenario ha mejorado la analgesia postoperatoria con aceptables márgenes de seguridad, lo que le ha servido para colocarse en un lugar predominante entre las pautas analgésicas de las Unidades de Dolor Agudo (UDA. La analgesia epidural con anestésicos locales y opioides frente a la sistémica con opioides ha presentado históricamente una superior eficacia analgésica, y una disminución de complicaciones derivadas de la atenuación del estrés quirúrgico y de la mejora en la función cardiorrespiratoria. Sin embargo, frente a estas ventajas la analgesia epidural también presenta inconvenientes como la hipotensión arterial o la retención urinaria, junto a las potencialmente graves derivadas del daño neurológico ocasionado por un hematoma epidural, una infección o una lesión directa del tejido nervioso. Si sus ventajas han resultado consistentes y fundamentadas, en este momento no lo parecen tanto. El avance que ha supuesto la cirugía mínimamente invasiva con altas más precoces, junto al desarrollo de estrategias multimodales, está conduciendo a un replanteamiento de la utilización de técnicas como la epidural y a una reevaluación de sus indicaciones. Las últimas evidencias nos inducen a pensar que la epidural probablemente haya tocado techo en el tratamiento del dolor postoperatorio y comenzará a perder terreno frente a otras técnicas igualmente efectivas, con menores complicaciones y efectos secundarios. Este será un proceso lento en el que deberá quedar asegurado que las alternativas analgésicas ofrecen realmente mejores resultados en cuanto a eficacia, seguridad, tolerabilidad y calidad de la recuperación desde la perspectiva del paciente.

    Full Text Available Existe un interés creciente por la realización de los bloqueos de nervio periférico (BNP debido a sus potenciales beneficios como los concernientes a las interacciones de los fármacos anticoagulantes y los bloqueos neuroaxiales. Los BNP de la extremidad inferior, y sobre todo, los bloqueos periféricos del nervio ciático son el pariente pobre de las técnicas de anestesia regional y, en general, son poco conocidos y por tanto poco utilizados. En este artículo se realiza una revisión de los bloqueos del plexo lumbosacro, realizando especial énfasis en los bloqueos continuos mediante catéteres para analgesia postoperatoria y para el tratamiento del dolor crónico. La utilización de anestésicos locales de larga duración de acción, asociada a un escaso bloqueo motor, como es el caso de la ropivacaína, nos permite combinar técnicas de punción única para conseguir una adecuada analgesia intraoperatoria, con las técnicas de perfusión continua para analgesia postoperatoria. Es necesario un conocimiento anatómico preciso, así como de los territorios cutáneos de inervación de las ramas del plexo lumbosacro, para la realización de estas técnicas de bloqueo. La introducción de diferentes técnicas de imagen, fundamentalmente la ultrasonografía, para la localización de las estructuras nerviosas, facilita la realización de estos bloqueos y disminuye el riesgo de lesiones de los órganos adyacentes. La realización de los bloqueos continuos de nervio periférico ofrece el beneficio de una analgesia postoperatoria prolongada, con menores efectos adversos, mayor grado de satisfacción del paciente, y una recuperación funcional más rápida después de la cirugía.There is increasing interest in peripheral nerve blocks (PNB because of potential benefits relative to interactions of anticoagulants and central neuraxial techniques.

    The endogenous analgesia (EA) system is psychophysically evaluated using various paradigms, including conditioned pain modulation (CPM) and offset analgesia (OA) testing, respectively, the spatial and temporal filtering processes of noxious information. Though both paradigms assess the function of the EA system, it is still unknown whether they reflect the same aspects of EA and consequently whether they provide additive or equivalent data. Twenty-nine healthy volunteers (15 males) underwent 5 trials of different stimulation conditions in random order including: (1) the classic OA three-temperature stimulus train ('OA'); (2) a three-temperature stimulus train as control for the OA ('OAcon'); (3) a constant temperature stimulus ('constant'); (4) the classic parallel CPM ('CPM'); and (5) a combination of OA and CPM ('OA + CPM'). We found that in males, the pain reduction during the OA + CPM condition was greater than during the OA (P = 0.003) and CPM (P = 0.07) conditions. Furthermore, a correlation was found between OA and CPM (r = 0.62, P = 0.01) at the time of maximum OA effect. The additive effect found suggests that the two paradigms represent at least partially different aspects of EA. The moderate association between the CPM and OA magnitudes indicates, on the other hand, some commonality of their underlying mechanisms.

    estudios en un área con tantas lagunas de conocimiento en nuestro medio.This is a first-time study in Brazil, which identified the relations between the analgesic standard and trauma severity. To do this, an analysis was performed in a population of 200 traffic accident victims admitted for treatment at the emergency unit of a referral hospital for trauma care in the city of São Paulo. Trauma and lesion severity were characterized by anatomic severity indexes. Based on the analysis of the analgesic therapy, analgesia standards were constructed, founded on the World Health Organization analgesic scale. The results permitted to identify the statistic association between trauma severity and distinct analgesia standards. The dissemination of these findings could serve as the basis to design analgesia protocols in trauma and improve care quality, besides encouraging the development of studies in an area with so many knowledge gaps.

MÉTODOS: Sesenta pacientes sometidos a procedimientos de toracotomía electiva fueron aleatoriamente ubicados en cuatro grupos con el uso de la técnica de sobres lacrados. Los grupos MIV, ME, MEB y MER recibieron morfina controlada por el paciente por vía intravenosa, epidural, morfina-bupivacaína y morfina-ropivacaína, respectivamente. La frecuencia cardíaca, presión arterial y la saturación de oxígeno perioperatorias y el dolor postoperatorio en reposo y durante la tos, los efectos colaterales y la necesidad de analgésicos de rescate fueron registrados a los 30 y 60 minutos y las 2, 4, 6, 12, 24, 36, 48 y 72 horas. RESULTADOS: La necesidad de sodio diclofenaco durante el estudio fue menor en el grupo ME. El área bajo la curva de tiempo en la VAS fue menor en el grupo ME en comparación con el Grupo MIV, pero similar al Grupo MEB y MER. Las puntuaciones de dolor en reposo fueron mayores en los tiempos 12, 24, 36 y 48 horas en el Grupo MIV en comparación con el grupo ME. Las puntuaciones de dolor en reposo fueron mayores a los 30 y 60 minutos en los Grupos ME y MIV en comparación con el Grupo MEB. Las puntuaciones de dolor durante la tos a los 30 minutos fueron mayores en el grupo ME en comparación con el Grupo MEB. No hubo diferencia entre los Grupos MIV y MER. CONCLUSIONES: La morfina administrada por vía epidural fue más eficaz que por la vía intravenosa. La eficacia fue mayor en el grupo EM en el período postoperatorio tardío y en el Grupo MEB en el período postoperatorio inicial. Concluimos entonces que la morfina administrada por vía epidural fue la más eficaz y nuestra preferida.BACKGROUND AND OBJECTIVEs: The aim of this randomized, double-blinded, prospective study was to determine the effectiveness and side effects of intravenous or epidural use of morphine, bupivacaine or ropivacaine on post-thoracotomy pain management

    Continuous interscalene brachial plexus blockade can provide anesthesia and analgesia in the shoulder region. Difficulty accessing the interscalene space and premature displacement of interscalene catheters may preclude their use in certain situations. We present two case reports in which a catheter was advanced from the axilla along the brachial plexus sheath to the interscalene space to provide continuous cervicobrachial plexus analgesia. In the first case report, previous neck surgery made the anatomic landmarks for performing an interscalene block very difficult. An epidural catheter was advanced from the axillary brachial plexus sheath to the interscalene space under fluoroscopic guidance. This technique provided both intraoperative analgesia for shoulder surgery as well as 24-hour postoperative analgesia by an infusion of 0.125% bupivacaine. In the second case report, a catheter was inserted in a similar fashion from the axillary to the interscalene space to provide 14 days of continuous analgesia in the management of complex regional pain syndrome. We have found that this technique allows us to secure the catheter more easily than with the traditional interscalene approach and thus prevents premature dislodgment. This approach may be a suitable alternative when either an interscalene or an infraclavicular catheter may not be inserted. PMID:11090734

    2012-02-03

    PURPOSE: This two-part review summarizes the current knowledge of physiological mechanisms, pharmacological modalities and controversial issues surrounding preemptive analgesia. SOURCE: Articles from 1966 to present were obtained from the MEDLINE databases. Search terms included analgesia, preemptive; neurotransmitters; pain, postoperative; hyperalgesia; sensitization, central nervous system; pathways, nociception; anesthetic techniques; analgesics, agents. Principal findings: In Part I of this review article, techniques and agents that attenuate or prevent central and peripheral sensitization were reviewed. In Part II, the conditions required for effective preemptive techniques are evaluated. Specifically, preemptive analgesia may be defined as an antinociceptive treatment that prevents establishment of altered central processing of afferent input from sites of injury. The most important conditions for establishment of effective preemptive analgesia are the establishment of an effective level of antinociception before injury, and the continuation of this effective analgesic level well into the post-injury period to prevent central sensitization during the inflammatory phase. Although single-agent therapy may attenuate the central nociceptive processing, multi-modal therapy is more effective, and may be associated with fewer side effects compared with the high-dose, single-agent therapy. CONCLUSION: The variable patient characteristics and timing of preemptive analgesia in relation to surgical noxious input require individualization of the technique(s) chosen. Multi-modal analgesic techniques appear more effective.

    PURPOSE: This two-part review summarizes the current knowledge of physiological mechanisms, pharmacological modalities and controversial issues surrounding preemptive analgesia. SOURCE: Articles from 1966 to present were obtained from the MEDLINE databases. Search terms included: analgesia, preemptive; neurotransmitters; pain, postoperative; hyperalgesia; sensitization, central nervous system; pathways, nociception; anesthetic techniques; analgesics, agents. Principal findings: The physiological basis of preemptive analgesia is complex and involves modification of the pain pathways. The pharmacological modalities available may modify the physiological responses at various levels. Effective preemptive analgesic techniques require multi-modal interception of nociceptive input, increasing threshold for nociception, and blocking or decreasing nociceptor receptor activation. Although the literature is controversial regarding the effectiveness of preemptive analgesia, some general recommendations can be helpful in guiding clinical care. Regional anesthesia induced prior to surgical trauma and continued well into the postoperative period is effective in attenuating peripheral and central sensitization. Pharmacologic agents such as NSAIDs (non-steroidal anti-inflammatory drugs) opioids, and NMDA (N-methyl-D-aspartate) - and alpha-2-receptor antagonists, especially when used in combination, act synergistically to decrease postoperative pain. CONCLUSION: The variable patient characteristics and timing of preemptive analgesia in relation to surgical noxious input requires individualization of the technique(s) chosen. Multi-modal analgesic techniques appear most effective.

    Full Text Available La analgesia epidural se ha convertido en una técnica rutinaria en el manejo perioperatorio de los pacientes quirúrgicos que se ha extendido fuera de los quirófanos y de las unidades de alta dependencia hacia las salas de hospitalización. La irrupción en este nuevo escenario ha mejorado la analgesia postoperatoria con aceptables márgenes de seguridad, lo que le ha servido para colocarse en un lugar predominante entre las pautas analgésicas de las Unidades de Dolor Agudo (UDA. La analgesia epidural con anestésicos locales y opioides frente a la sistémica con opioides ha presentado históricamente una superior eficacia analgésica, y una disminución de complicaciones derivadas de la atenuación del estrés quirúrgico y de la mejora en la función cardiorrespiratoria. Sin embargo, frente a estas ventajas la analgesia epidural también presenta inconvenientes como la hipotensión arterial o la retención urinaria, junto a las potencialmente graves derivadas del daño neurológico ocasionado por un hematoma epidural, una infección o una lesión directa del tejido nervioso. Si sus ventajas han resultado consistentes y fundamentadas, en este momento no lo parecen tanto. El avance que ha supuesto la cirugía mínimamente invasiva con altas más precoces, junto al desarrollo de estrategias multimodales, está conduciendo a un replanteamiento de la utilización de técnicas como la epidural y a una reevaluación de sus indicaciones. Las últimas evidencias nos inducen a pensar que la epidural probablemente haya tocado techo en el tratamiento del dolor postoperatorio y comenzará a perder terreno frente a otras técnicas igualmente efectivas, con menores complicaciones y efectos secundarios. Este será un proceso lento en el que deberá quedar asegurado que las alternativas analgésicas ofrecen realmente mejores resultados en cuanto a eficacia, seguridad, tolerabilidad y calidad de la recuperación desde la perspectiva del paciente

    1985-03-01

    Pentobarbital pretreatment reportedly either inhibits, enhances or has no effect on morphine analgesia. The effect of subanesthetic doses of sodium pentobarbital (8-12 mg kg-1, SC) delivered via a delivery system on analgesia of morphine (5 mg kg-1, SC or 1 mg kg-1, IV) acutely administered 45 min after the sodium pentobarbital pellet implantation was assessed using the warm water (55 degrees C)-induced tail-withdrawal reflex in male Wistar rats. Significant potentiation of morphine analgesia was observed in sodium pentobarbital as compared to the placebo-pelleted animals. Pharmacokinetic or dispositional factors were not involved in this potentiation, which was possibly due to the activation of the descending inhibitory control pathways of nociceptive spinal tail-withdrawal reflex by a combined interaction of two drugs at spinal and supraspinal sites of action, that mediate opiate antinociception.

    Miguez, Gonzalo; Laborda, Mario A; Miller, Ralph R

    2014-01-01

    This article reviews situations in which stimuli produce an increase or a decrease in nociceptive responses through basic associative processes and provides an associative account of such changes. Specifically, the literature suggests that cues associated with stress can produce conditioned analgesia or conditioned hyperalgesia, depending on the properties of the conditioned stimulus (e.g., contextual cues and audiovisual cues vs. gustatory and olfactory cues, respectively) and the proprieties of the unconditioned stimulus (e.g., appetitive, aversive, or analgesic, respectively). When such cues are associated with reducers of exogenous pain (e.g., opiates), they typically increase sensitivity to pain. Overall, the evidence concerning conditioned stress-induced analgesia, conditioned hyperalagesia, conditioned tolerance to morphine, and conditioned reduction of morphine analgesia suggests that selective associations between stimuli underlie changes in pain sensitivity.

  15. The neuroanatomy of sexual dimorphism in opioid analgesia.

    2014-09-01

    The influence of sex has been neglected in clinical studies on pain and analgesia, with the vast majority of research conducted exclusively in males. However, both preclinical and clinical studies indicate that males and females differ in both the anatomical and physiological composition of central nervous system circuits that are involved in pain processing and analgesia. These differences influence not only the response to noxious stimuli, but also the ability of pharmacological agents to modify this response. Morphine is the most widely prescribed opiate for the alleviation of persistent pain in the clinic; however, it is becoming increasingly clear that morphine is less potent in women compared to men. This review highlights recent research identifying neuroanatomical and physiological dimorphisms underlying sex differences in pain and opioid analgesia, focusing on the endogenous descending pain modulatory circuit.

    2012-01-31

    We report the successful use of a stellate ganglion block as part of a multi-modal postoperative analgesic regimen. Four patients scheduled for orthopaedic surgery following upper limb trauma underwent blockade of the stellate ganglion pre-operatively under ultrasound guidance. Patients reported excellent postoperative analgesia, with postoperative VAS pain scores between 0 and 2, and consumption of morphine in the first 24 h ranging from 0 to 14 mg. While these are preliminary findings, and must be confirmed in a clinical trial, they highlight the potential for stellate ganglion blockade to provide analgesia following major upper limb surgery.

    Abstract Background: The surgical pleth index (SPI) is proposed for titration of analgesic drugs during general anesthesia. Several reports have investigated the effect of SPI on the consumption of opioids including remifentanil, fentanyl, and sufentanil during anesthesia, but there are no reports about oxycodone. We aimed to investigate intravenous oxycodone consumption between SPI-guided analgesia and conventional analgesia practices during sevoflurane anesthesia in patients undergoing thyroidectomy. Methods: Forty-five patients undergoing elective thyroidectomy were randomly assigned to an SPI group (SPI-guided analgesia group, n = 23) or a control group (conventional analgesia group, n = 22). Anesthesia was maintained with sevoflurane to achieve bispectral index values between 40 and 60. In the SPI group, oxycodone 1 mg was administered intravenously at SPI values over 50; in the control group, oxycodone 1 mg was administered intravenously at the occurrence of tachycardia or hypertension event. Intraoperative oxycodone consumption and extubation time were recorded. The number of hemodynamic and somatic movement events was recorded, as were postoperative pain and recovery scores. Results: Patients’ characteristics were comparable between the groups. Intraoperative oxycodone consumption in the SPI group was significantly lower than the control group (3.5 ± 2.4 vs 5.1 ± 2.4 mg; P = 0.012). Extubation time was significantly shorter in the SPI group (10.6 ± 3.5 vs 13.4 ± 4.6 min; P = 0.026). Hemodynamic and somatic movement events during anesthesia were comparable between the groups, as were numeric rating scales for pain and modified Aldrete scores at postanesthesia care unit. Conclusions: SPI-guided analgesia reduces intravenous oxycodone consumption and extubation time compared with conventional analgesia based on clinical parameters during sevoflurane anesthesia in patients undergoing thyroidectomy.

    Standard care of burn wounds consists of cleaning and debridement (removing devitalized tissue), followed by daily dressing changes. Children with burns undergo multiple, painful and anxiety-provoking procedures during wound care and rehabilitation. The goal of procedural sedation is safe and efficacious management of pain and emotional distress, requiring a careful and systematic approach. Achieving the best results needs understanding of the mechanisms of pain and the physiologic changes in burn patients, frequent evaluation and assessment of pain and anxiety, and administration of suitable pharmacological and nonpharmacological therapies. Pharmacological therapies provide the backbone of analgesia and sedation for procedural pain management. Opioids provide excellent pain control, but they must be administered judiciously due to their side effects. Sedative drugs, such as benzodiazepines and propofol, provide excellent sedation, but they must not be used as a substitute for analgesic drugs. Ketamine is increasingly used for analgesia and sedation in children as a single agent or an adjuvant. Nonpharmacological therapies such as virtual reality, relaxation, cartoon viewing, music, massage and hypnosis are necessary components of procedural sedation and analgesia for children. These can be combined with pharmacological techniques and are used to limit the use of drugs (and hence side effects), as well as to improve patient participation and satisfaction. In this article, we review the pathophysiologic changes associated with major thermal injury in children, the options available for sedation and analgesia for wound care procedures in these children and our institutional guidelines for procedural sedation.

Bupivacaine, a commonly used analgesic, has been formulated into an aqueous suspension of multivesicular liposomes that provide long-lasting analgesia for up to 72 hours, while avoiding the adverse side effects of opioids. The increased efficacy of liposomal extended-release bupivacaine, compared to bupivacaine hydrochloride, has promoted its usage in a variety of surgeries including hemorrhoidectomy, bunionectomy, inguinal hernia repair, total knee arthroplasty, and augmentation mammoplasty. However, like other bupivacaine formulations, the liposomal extended-release bupivacaine does have some side effects. In this brief review, we provide an update of the current knowledge in the use of bupivacaine for postsurgical analgesia.

    2013-08-01

    Adequate pain relief is usually achieved with the simultaneous use of two or more different classes of analgesics, often called multimodal analgesia. The purpose of this article is to highlight the use of perioperative multimodal analgesia and the need to individualize the treatment plan based on the presenting condition, and to adjust it based on the response to analgesia for a given patient. This case series presents the alleviation of acute pain in three cats undergoing different major surgical procedures. These cases involved the administration of different classes of analgesic drugs, including opioids, non-steroidal anti-inflammatory drugs, tramadol, ketamine, gabapentin and local anesthetics. The rationale for the administration of analgesic drugs is discussed herein. Each case presented a particular challenge owing to the different cause, severity, duration and location of pain. Pain management is a challenging, but essential, component of feline practice: multimodal analgesia may minimize stress while controlling acute perioperative pain. Individual response to therapy is a key component of pain relief in cats. PMID:23382595

    BACKGROUND AND OBJECTIVE: The last 25 years have seen changes in the management of epidural analgesia for labour, including the advent of low-dose epidural analgesia, the development of new local anaesthetic agents, various regimes for maintaining epidural analgesia and the practice of combined spinal-epidural analgesia. We conducted a survey of Irish obstetric anaesthetists to obtain information regarding the conduct and management of obstetric epidural analgesia in Ireland in 2005. The specific objective of this survey was to discover whether new developments in obstetric anaesthesia have been incorporated into clinical practice. METHODS: A postal survey was sent to all anaesthetists with a clinical commitment for obstetric anaesthesia in the sites approved for training by the College of Anaesthetists, Ireland. RESULTS: Fifty-three per cent of anaesthetists surveyed responded. The majority of anaesthetists (98%) use low-dose epidural analgesia for the maintenance of analgesia. Only 11% use it for test-dosing and 32% for the induction of analgesia. The combined spinal-epidural analgesia method is used by 49%, but two-thirds of those who use it perform fewer than five per month. Patient-controlled epidural analgesia was in use at only one site. CONCLUSION: It appears that Irish obstetric anaesthetists have adopted the low-dose epidural analgesia trend for the maintenance of labour analgesia. This practice is not as widespread, however, for test dosing, the induction of analgesia dose or in the administration of intermittent epidural boluses to maintain analgesia when higher concentrations are used. Since its introduction in 2000, levobupivacaine has become the most popular local anaesthetic agent.

    Full Text Available OBJETIVO: el objetivo de este estudio consistió en analizar si existen diferencias en la gestión preventiva llevada a cabo en varias empresas que presentaron enfermedades profesionales en función del género de los trabajadores. MÉTODOS: se analizó una muestra de 302 trabajadores, siendo el 31,1% mujeres, de empresas donde se había declarado enfermedad profesional en la provincia de Valencia (España. Los datos se recogieron mediante un cuestionario con 40 preguntas. RESULTADOS: los resultados indicaron que en estas empresas se realizaba una gestión preventiva en la que el plan de prevención y la participación de los trabajadores eran las actividades que con menor frecuencia se aplicaban, y en el caso de las mujeres la gestión preventiva llevada a cabo resultaba significativamente peor que para los hombres. CONCLUSIONES: se concluye que con referencia a la prevención de riesgos laborales el género puede ser una variable que genera una discriminación negativa hacia las mujeres trabajadoras. Además, los riesgos laborales y los problemas de salud asociados deberían ser considerados un problema de salud pública.

    2016-02-01

    Total knee arthroplasty is associated with substantial postoperative pain that may impair mobility, reduce the ability to participate in rehabilitation, lead to chronic pain, and reduce patient satisfaction. Traditional general anesthesia with postoperative epidural and patient-controlled opioid analgesia is associated with an undesirable adverse-effect profile, including postoperative nausea and vomiting, hypotension, urinary retention, respiratory depression, delirium, and an increased infection rate. Multimodal anesthesia--incorporating elements of preemptive analgesia, neuraxial perioperative anesthesia, peripheral nerve blockade, periarticular injections, and multimodal oral opioid and nonopioid medications during the perioperative and postoperative periods--can provide superior pain control while minimizing opioid-related adverse effects, improving patient satisfaction, and reducing the risk of postoperative complications.

    Cocaine hydrochloride (50 mg) pellets implanted subcutaneously in male Wistar rats potentiated the analgesia of morphine, levorphanol, methadone and buprenorphine as measured by the tail-withdrawal test. Potentiated opiate analgesia was abolished by naloxone and further enhanced by desipramine and phenoxybenzamine. Yohimbine, alpha-methyl p-tyrosine, haloperidol, zimelidine, methysergide, p-chlorophenylalanine produced no significant effect on potentiated opiate analgesia. Pseudo-cocaine (dextro-cocaine), which is several-fold less potent than cocaine as an inhibitor of noradrenaline and dopamine reuptake in the CNS, had no significant effect on opiate analgesia. Analgesia produced by low doses of baclofen, a GABA agonist, was also not potentiated by cocaine. This study suggests a predominant role for noradrenaline in the stereospecific potentiation of opiate analgesia by cocaine. PMID:3822492

MÉTODO: Participaron del estudio aleatorio y duplamente encubierto 40 pacientes, de ambos sexos, con edad variando de 18 a 50 años, peso entre 50 y 100 kg, estado físico ASA I y II, sometidos a colecistectomía por vía subcostal, los cuales fueron distribuidos en dos grupos: clonidina (GC, en que fue administrada clonidina (1 ml = 150 µg asociada a ropivacaína a 0,75% (20 ml por vía peridural; dexmedetomidina (GD, en que fue inyectada dexmedetomidina (2 µg.kg-1 asociada a ropivacaína a 0,75% (20 ml por vía peridural. La analgesia y la sedación fueron observadas 2, 6 y 24 horas después del término de la anestesia. RESULTADOS: Ocurrió sedación después de 2 y 6 horas en ambos grupos, siendo que hubo diferencia estadística significante entre los tiempos de 2 y 6 horas en el grupo dexmedetomidina. Hubo analgesia en ambos grupos, especialmente después de 2 y 6 horas. Fue detectada diferencia estadística significante entre los tiempos de 2, 6 y 24 horas en el grupo dexmedetomidina; en el grupo clonidina esa diferencia estadística significante fue observada entre los tiempos de 2 y 6 horas y entre 2 y 24 horas. CONCLUSIONES: Los resultados permitieron concluir que la clonidina o la dexmedetomidina asociadas a ropivacaína a 0,75% aseguraron analgesia y sedación en los tiempos de observación de 2 y 6 horas después del término de la anestesia, en los pacientes sometidos a la colecistectomia por vía subcostal y que la clonidina promueve analgesia más prolongada.BACKGROUND AND OBJECTIVES: Clonidine and dexmedetomidine are alpha2-adrenergic agonists with analgesic proprieties which potentiate

    Full Text Available The study investigates parturients’ satisfaction with intrapartum analgesia. It aims to assess their opinions about hospital and health staff involved in delivery, besides investigating emotional control, locus control and bond between mothers and their newborn infants. A multidimensional approach has been used to investigate the variable of woman as a person, the variable of context and the variable of bond with the newborn infant. The study was conducted according to a quasi-experimental design, with a control group. The study was performed within the Analgesia and Intensive Care Operational Unit of the Maternal-Infant Department of the P. Giaccone University General Hospital of Palermo. It involved 60 women subdivided into two groups of 30 women each, the experimental group (women who requested intrapartum analgesia called the A group, and the control group (women who refused it called the B group. The following tools were administered: the STAI-Y (State-Trait Anxiety Inventory, form Y scale; the Depression Questionnaire of CBA (Cognitive Behavioural Assessment scale; the Locus of Control questionnaire; and an interview designed for the purpose. The experimental A group women exhibited lower levels of state anxiety and depression post-partum than those of the control B group; moreover, the women in the A group exhibited higher levels of external locus of control and evaluated delivery more positively than those of the B group. There were no significant differences with regard to the relationship with their newborn infants. The study shows that intrapartum analgesia provides hospitals with the possibility to satisfy women’s needs for safety and well-being.

    Severe postsurgical pain contributes to prolonged hospital stay and is also believed to be a risk factor for the development of chronic pain. Locoregional anesthesia, which results in faster patient recovery with fewer side effects, is favored wherever feasible, but is not applicable to every patient. Systemic analgesics are the most widely used method for providing pain relief in the postoperative period. Improvements in postoperative systemic analgesia for pain management should be applied and predictive factors for severe postoperative pain should be anticipated in order to control pain while minimizing opioid side effects. Predictive factors for severe postoperative pain include severity of preoperative pain, prior use of opiates, female gender, non-laparoscopic surgery, and surgeries involving the knee and shoulder. Pre- and intraoperative use of small doses of ketamine has a preventive effect on postoperative pain. Multimodal or balanced analgesia (the combined use of various analgesic agents) such as NSAID/morphine, NSAID/nefopam, morphine/ketamine improves analgesia with morphine-sparing effects. Nausea and vomiting, the principle side effects of morphine, can be predicted using Apfel's simplified score; patients with a high Apfel score risk should receive preemptive antiemetic agents aimed at different receptor sites, such as preoperative dexamethasone and intraoperative droperidol. Droperidol can be combined with morphine for postoperative patient-controlled anesthesia (PCA). When PCA is used, dosage parameters should be adjusted every day based on pain evaluation. Patients with presurgical opioid requirements will require preoperative administration of their daily opioid maintenance dose before induction of anesthesia: PCA offers useful options for effective postsurgical analgesia using a basal rate equivalent to the patient's hourly oral usage plus bolus doses as required.

    Two thirds of patients suffer from moderate to severe pain after frontotemporal craniotomy. We think neurosurgeons must try to reduce the postoperative pain, which may induce postoperative hypertension, restlessness, and pathological pains. To investigate how preemptive analgesia effects postoperative pain, we assessed the pain in 20 consecutive patients who underwent neck clipping for non-ruptured cerebral aneurysms of anterior circulation systems by frontotemporal craniotomies. Ten patients underwent preemptive analgesia with four procedures (preemptive group) as follows, 1) oral administration of long-acting non-steroid anti inflammatory drug (NSAID, ampiroxicam) two hours before the surgical operation, 2) nerve blockades of the supra-orbital nerve and the infra-orbital nerve by bupivacaine, 3) local anesthesia of the scalp along the marker of a skin incision by xylocaine, 4) local anesthesia by bupivacaine along a skin incision after the skin closure. Ten patients of the control group underwent only procedure No. 3. Visual analog pain score (VAS) for postoperative pain 6, 12, and 24 hours, and 3, 5, 7, and 14 days after operation and NSAID administration for the pain were evaluated. Patients of the preemptive group had significantly less postoperative pain during the whole post-surgery period and required less administration of NSAID than the control group. Preemptive analgesia procedures No. 1, 2 and 4 reduced the postoperative pain and the total administration of NSAID. Postoperative pain may be reduced after other types of brain surgery, with proper nerve blocks like procedure No. 2, procedures No. 1, 3 and 4. PMID:11857941

    Full Text Available Patient controlled epidural analgesia (PCEA is a well established technique for pain relief during labor. But the inclusion of continuous background infusion to PCEA is controversial. The aim of this study was to assess whether the use of continuous infusion along with PCEA was beneficial for laboring women with regards to quality of analgesia, maternal satisfaction and neonatal outcome in comparison to PCEA alone. Fifty five parturients received epidural bolus of 10ml solution containing 0.125% bupivacaine +2 ìg.ml-1 of fentanyl. For maintenance of analgesia the patients of Group PCEA self administered 8 ml bolus with lockout interval of 20 minutes of above solution on demand with no basal infusion. While the patients of Group PCEA + CI received continuous epidural infusion at the rate of 10 ml.hr-1 along with self administered boluses of 3 ml with lockout interval of 10 minutes of similar epidural solution. Patients of both groups were given rescue boluses by the anaesthetists for distressing pain. Verbal analogue pain scores, incidence of distressing pain, need of supplementary/rescue boluses, dose of bupivacaine consumed, maternal satisfaction and neonatal Apgar scores were recorded. No significant difference was observed between mean VAS pain scores during labor, maternal satisfaction, mode of delivery or neonatal Apgar scores. But more patients (n=8 required rescue boluses in PCEA group for distressing pain. The total volume consumed of bupivacaine and opioid was slightly more in PCEA + CI group. In both the techniques the highest sensory level, degree of motor block were comparable& prolongation of labor was not seen. It was concluded that both the techniques provided equivalent labor analgesia, maternal satisfaction and neonatal Apgar scores. PCEA along with continuous infusion at the rate of 10 ml/ hr resulted in lesser incidence of distressing pain and need for rescue analgesic. Although this group consumed higher dose of bupivacaine

    Objective To evaluate the safety and analgesic efficacy of patient controlled intravenous analgesia (PCIA) with tramadol, and to compare its benefits and risks with combined spinal-epidural analgesia (CSEA)+ patient controlled epidural analgesia (PCEA). Methods Eighty American Society of Anesthesiologist (ASA) Ⅰ-Ⅱ at term parturients in active labor were randomly divided into 3 groups: the control group (n=30) received no analgesia; group A (n=30) received spinal administration with ropivacaine 2.5 mg and fentanyl 5 μg, then with PCEA; group B (n=20) received 1 mg/kg tramadol loading dose I.v.. PCIA with 0.75% tramadol and it included: PCA dose 2 ml, lockout time 10 minutes, background infusion 2 ml/h, total dose no more than 400 mg. The intensity of pain was evaluated using Visual Analogue Scale (VAS). Results Both group A and B showed good pain relief. VAS pain scores were significantly decreased in group A and B compared with those in the control group (P<0.01). In comparison with group B, the VAS pain scores decreased in group A (P<0.05). The onset times of analgesia in group A were shorter than those in group B (P<0.05). Apgar scores in group B were lower than those in group A (P<0.05). The periods of second stage of labor in group A were longer than those in the control group and group B (P<0.05). The cesarean delivery rate was significantly higher in the control group (16.7%) than in group A (3.3%) and group B (5.0%), but it did not differ between group A and B. There were no significant differences in vital signs, fetal heart rate, degree of motor block, and uterine contractions among the 3 groups. Conclusions PCIA with tramadol is now a useful alternative when patients are not candidates for CSEA for labor, or do not want to have a neuraxial block anesthesia. However, sometimes it may not provide satisfactory analgesic effect.

Todas recibieron sedación pre-operatoria con midazolan. Un de los grupos (P recibió antes de iniciar la cirugía 40 mg de parecoxib y en el otro (T 20 mg de tenoxican. En la sala de operación fue hecha raquianestesia con bupivacaína y sufentanil. La analgesia pos-operatoria fue evaluada mediante la intensidad del dolor con escalas verbal y visual, localización del dolor (incisional, visceral, en el hombro y el consumo de analgésicos suplementares. Fueron registrados los efectos colaterales adversos La satisfacción de la paciente con la técnica fue pesquisada. RESULTADOS: La calidad analgésica fue excelente, con 76% de las pacientes del grupo P y 83% de las pacientes del grupo T sin queja de dolor y tampoco el uso de analgésicos en el pos-operatorio. No hubo diferencia entre los grupos en todos los criterios y períodos de evaluación analgésica. La incidencia de efectos adversos fue pequeña, no obstante, prurito de intensidad leve y de corta duración ocurrió frecuentemente. Todas las pacientes quedaron satisfechas o también muy satisfechas con la técnica empleada. CONCLUSIONES: Una técnica de analgesia multimodal, con un componente de anestésico local y opioide por vía subaracnóidea asociado con AINE venoso produce analgesia pos-operatoria de excelente calidad con pocos efectos colaterales adversos en cirugía videolaparoscópica ginecológica ambulatorial.

    Full Text Available Background: Spinal analgesia is one of the effective and rapid methods for labor. It is not commonly used because of short duration of analgesia and motor block, which limits mother's force in labor progression. We attempted to prolong duration and quality of analgesia by adding Epinephrine.Methods: In this quasi-experimental study 90 pregnant women gravid II and III who referred to Motazedi and Imam Reza Educational & Medical Centers were recruited and divided into two groups of case and control (45 subjects in each group. The case group received spinal analgesia using Sufentanil and Bupivacaine, and Epinephrine while the control group received Sufentanil and Bupivacaine. Data including feeling of pain, motor block, duration of analgesia, fetal heart rate, nausea and vomiting, blood pressure was collected and analyzed using chi-square and t test. Results: duration of analgesia and vomiting were significantly increased in the case group. (p=0.001, p=0.01 respectively. Hemodynamic status in mothers and Apgar score of neonates were not significantly different between two groups.Conclusion: It seems that adding Epinephrine to Sufentanil and Bupivacaine could increase analgesia duration without altering in sensory level although could increase nausea and vomiting its recommended in labor analgesia.

    Full Text Available Background: Epidural analgesia is a central nerve block technique achieved by injection of a local anaesthetic close to the nerves that transmit pain and is widely used as a form of pain relief in labor. Epidural analgesia is the most effective method of pain relief during labor. But unfortunately in India incidence of painless labor by epidural analgesia is very rare even in these days. The aim of our study was to study the acceptance of epidural analgesia at a tertiary care centre. Methods: The present study was conducted in department of obstetrics and gynaecology UISEMH, Kanpur over the period from May 2012 to May 2013. The study was conducted on 98 patients who were counselled regarding the adoption of epidural analgesia as painless labour and out of these 50 patients opted for epidural analgesia. Results: In our present study the acceptance was greater in primigravida (72.43% as compared to multigravida (20%. In our society social reason was the common cause for non-acceptance in primigravida (87.5%. The majority of patients belonged to middle socioeconomic status (52% and more number of educated patients opted for epidural analgesia. Conclusions: It was found that increased awareness can lead to increased acceptance of epidural analgesia. [Int J Reprod Contracept Obstet Gynecol 2014; 3(4.000: 1087-1089

    Full Text Available ABSTRACT INTRODUCTION: The currently common musculoskeletal disorders have been increasingly treated surgically, and the pain can be a limiting factor in postoperative rehabilitation. RATIONALE: Patient controlled analgesia (PCA controls pain, but its adverse effects can interfere with rehabilitation and in the patient discharge process. This study becomes important, since there are few studies evaluating this correlation. OBJECTIVES: To compare the outcomes of patients who used and did not use patient controlled analgesia in postoperative orthopedic surgery with respect to pain, unscheduled need for O2 (oxygen, and time of immobility and in-hospital length of stay. METHODS: This is an observational, prospective study conducted at Hospital Abreu Sodré from May to August 2012. The data was daily obtained through assessments and interviews of patients undergoing total hip arthroplasty (THA and total knee arthroplasty (TKA, thoracolumbar spine arthrodesis (long PVA, cervical spine arthrodesis (cervical AVA and lumbar spine arthrodesis (lumbar PVA. RESULTS: The study showed some differences between groups, namely: the painful level was higher in the group undergoing lumbar PVA without PCA compared with the group with PCA (p = 0.03 and in the group of long PVA without PCA in the early postoperative period. This latter group used O2 for a longer time (p = 0.09. CONCLUSION: In this study, PCA was useful for analgesia in patients undergoing lumbar PVA and probably would have influenced the usage time of O2 in the group of long PVA in face of a larger sample. The use of PCA did not influence the time of leaving the bed and the in-hospital length of stay for the patients studied.

This article reviews a novel, noninvasive modality that combines simultaneous imaging and treatment, thus taking advantage of the electrodermal information available from imaged ATPs to deliver localized neurostimulation, to stimulate peripheral nerve endings (Aδ fibers) and in turn, to release endogenous endorphins. "Hyperstimulation analgesia" with localized, intense, low-rate electrical pulses applied to painful ATPs was found to be effective in 95% patients with chronic nonspecific low back pain, in a clinical validation study.

    effects (nausea, dizziness, sedation, respiratory effects and itching) were registered. The postoperative opioid consumption varied considerably between the patients but the mean opioid consumption in the morphine and oxycodone group was comparable (18.93 mg versus 16.15 mg, P = 0.7). Nausea...... was significantly less frequent with morphine (P = 0.03). In this study morphine and oxycodone produced similar analgesia the first 4 h after surgery but the frequency of nausea was significantly less patient-reported with morphine.

    Full Text Available BACKGROUND Parenteral opioids and sedatives are the most frequently prescribed agents for women in labour in many poor resource settings. These have shown poor pain relief and a lot of side effects in both the mother and the foetus. In patients with severe pre-eclampsia who are already haemodynamically compromised labour pains and delivery can result in haemodynamic instability, which can compromise both the mother and the neonate. Dexmedetomidine is a highly selective α-2 agonist, which when used in recommended dose in the form of an infusion has several desirable properties like sedation, anxiolysis, sympatholysis, analgesia, decreased anaesthetic requirements, maintains cardiovascular stability and provides a smooth recovery. AIM The aim of this study was to study the haemodynamic effects of intravenous dexmedetomidine when used in patients with severe pre-eclampsia for labour analgesia. MATERIALS AND METHODS The study was conducted in the Department of Obstetrics and Gynaecology of Bundelkhand Medical College, Sagar, between January 2015 and December 2016; 40 labouring patients with severe pre-eclampsia were included in the study; 20 each were allocated to the study and control group. The study group received intravenous Dexmedetomidine in the recommended doses (1 ug/kg loading dose over 10-15 minutes followed by an infusion at 0.2-0.7 ug/kg/hour when in active labour, while the control group received Intravenous Fentanyl. The two groups were compared regarding the duration of labour, the mode of delivery, the neonatal outcome, the onset and duration of analgesia and maternal haemodynamic parameters during labour and delivery. The data obtained in this study was tabulated and analysed using the Chi-square test and the Z test with p value of 0.05 taken as significant. RESULTS It was found out that the group of patients who received Dexmedetomidine were more haemodynamically stable during labour and delivery; there was significant pain relief

    Deployment to a combat zone with the military poses many challenges to the anaesthetist. One of these challenges is the safe, rapid and comfortable initial wound management and repatriation of wounded combat soldiers to their home country or tertiary treatment facility for definitive care and rehabilitation. The current conflict in Afghanistan is associated with injury patterns that differ from wars such as Vietnam or Korea. This report describes the experience of an Australian military anaesthetist and the value of regional anaesthesia and analgesia for the care of the wounded combat soldier

    Glanzmann thrombastenia (GT) is a rare condition of an inherited autosomal recessive gene characterized with bleeding tendency. The condition is rarely met in the OR. and therefore it is essential that anesthesiologist be cognizant of the risk involved and be prepared with all necessary precautionary measures. We present a GT case in a 27-year-old male with a mass in the anticubital region of right wrist that was successfully excised using the non-invasive intravenous regional analgesia (IVRA). The use of platelet transfusion and the recombinant factor VIIa, are stressed.

    The major gynecology surgery generally results in severe postoperative pain. Currently multimodal analgesia concept is widely used for the aim of postoperative pain relief optimization. According to this theory it is worth using the medication with different mechanism in order to increase analgesia qualify, decrease analgesic consumption and avoid adverse reaction. Unfortunately the surveys recently conducted have been pointed out the postoperative analgesia quality is still insufficient despite of using the concept mentioned above. One way to solve the problem is appearing in daily practice nefopam--centrally acting non-opioid analgesic that inhibits reuptake of serotonin, norepinephrine, and dopamine and also mitigates glutamatergic neurotransmission. In this trial we tried to assess the postoperative daily used analgesia quality and potency of preemptive multimodal analgesia model consisted of nefopam, ketoprofen, paracetamol and morphine.

    Full Text Available Background: Neuraxial labor analgesia using new local anesthetics such as levobupivacaine has become very popular by virtue of the safety and lesser motor blockade caused by these agents. Combined spinal-epidural analgesia (CSEA has become the preferred method for labor analgesia as it combines benefits of both spinal analgesia and flexibility of the epidural catheter. Adding opioids to local anesthetic drugs provide rapid onset and prolonged analgesia but may be associated with several maternal and fetal adverse effects. The purpose of this study is to compare fentanyl and tramadol used in CSEA in terms of duration of analgesia and frequency of the adverse fetomaternal outcome. Materials and Methods: A total of 60 primiparas with a singleton pregnancy in active labor were given CSEA after randomly allocating them in two groups of 30 each. Group I received intrathecal 2.5 mg levobupivacaine + 25 μg fentanyl followed by epidural top ups of 20 ml 0.125% solution of the same combination. Group II received 25 mg tramadol instead of fentanyl. Epidural top ups were given when parturient complained of two painful contractions (visual analogue scale ≥ 4. Data collected were demographic profile of the patients, analgesic qualities, side- effects and the fetomaternal outcome. Results: Patients in Group II had significantly prolonged analgesia (145 ± 9 minutes than in Group I (95 ± 7 minutes. Patients receiving fentanyl showed rapid onset of analgesia, but there were more incidence of side-effects like shivering, pruritus, transient fetal bradycardia, hypotension, nausea and vomiting. Only side-effect in the tramadol group was nausea and vomiting. During labor, maternal satisfaction was excellent. Conclusions: Adding tramadol to local anesthetic provides prolonged analgesia with minimal side effects. Fentanyl, when used as adjuvant to local anesthetic, has a rapid onset of analgesia but has certain fetomaternal side-effects.

    Recently, regional anaesthesia in children has generated increasing interest. But single injection techniques have a limited duration of postoperative analgesia. Then, continuous peripheral nerve blocks have taken an important position in the anaesthetic arsenal, allowing an effective, safe and prolonged postoperative pain management. As adults, indications for continuous peripheral nerve blocks depend on the analysis of individual benefits/risks ratio. Main indications are intense postoperative pain surgical procedures, with or without postoperative rehabilitation, and complex regional pain syndrome. Contraindications to these procedures are rather similar to those in adults, plus parental and/or children refusal. Continuous peripheral nerve blocks are usually performed under general anaesthesia or sedation in children, and require appropriate equipment in order to decrease the risk of nerve injury. New techniques, such as transcutaneous nerve stimulation or ultrasound guidance, appeared to facilitate nerve and plexus approach identification in paediatric patients. Nevertheless, continuous peripheral nerve block may theoretically mask a compartment syndrome after trauma surgical procedures. Finally, ropivacaine appears to be the most appropriate drug for continuous peripheral nerve blocks in children, requiring low flow rates and concentrations of local anaesthetic. These techniques may facilitate early ambulation by an improved pain management or even postoperative analgesia at home with disposable pumps. One might infer from the current review that excellent pain relief coupled with a reduction of side effects would contribute to improve the quality of life and to decrease the frequency of disabling behavioural modifications in children, sometimes psychologically injured by hospital stay and postoperative pain.

    This study was conducted to determine whether exposure to RFR might induce sufficient thermal stress to activate endogenous opioid mechanisms and induce analgesia. Male Swiss Webster mice, 20-25 g, were exposed to 10, 15 or 20 mV/cm{sup 2} RFR in a 2,450-MHz waveguide system for 10 min, then tested in the abdominal constriction paradigm. Specific absorption rates (SAR) were 23.7 W/kg at 10 mW/cm{sup 2}, 34.6 W/kg at 15 mW/cm{sup 2} and 45.5 W/kg at 20 mW/cm{sup 2}. Confinement in the exposure chamber alone did not appreciably alter body temperature but did appear to induce a stress-associated analgesia that was insensitive to the opioid receptor blocker naltrexone. Exposure of confined mice to RFR elevated body temperature and further increased analgesia in SAR-dependent manner. The high-SAR RFR-induced analgesia, but not the hyperthermia, was reduced by naltrexone. These findings suggest that (1) RFR produces SAR-dependent hyperthermia and analgesia and (2) RFR-induced analgesia is mediated by opioid mechanisms while confinement-induced analgesia involves non-opioid mechanisms.

    Full Text Available Abstract Background Most women use some method of pain relief during labour. There is extensive research evidence available of pharmacological pain relief during labour; however this evidence is not readily available to pregnant women. Decision aids are tools that present evidence based information and allow preference elicitation. Methods We developed a labour analgesia decision aid. Using a RCT design women either received a decision aid or a pamphlet. Eligible women were primiparous, ≥ 37 weeks, planning a vaginal birth of a single infant and had sufficient English to complete the trial materials. We used a combination of affective (anxiety, satisfaction and participation in decision-making and behavioural outcomes (intention and analgesia use to assess the impact of the decision aid, which were assessed before labour. Results 596 women were randomised (395 decision aid group, 201 pamphlet group. There were significant differences in knowledge scores between the decision aid group and the pamphlet group (mean difference 8.6, 95% CI 3.70, 13.40. There were no differences between decisional conflict scores (mean difference -0.99 (95% CI -3.07, 1.07, or anxiety (mean difference 0.3, 95% CI -2.15, 1.50. The decision aid group were significantly more likely to consider their care providers opinion (RR 1.28 95%CI 0.64, 0.95. There were no differences in analgesia use and poor follow through between antenatal analgesia intentions and use. Conclusions This decision aid improves women's labour analgesia knowledge without increasing anxiety. Significantly, the decision aid group were more informed of labour analgesia options, and considered the opinion of their care providers more often when making their analgesia decisions, thus improving informed decision making.

    2013-01-01

    Full Text Available Pain remains a poorly understood and managed symptom. A limited mechanistic understanding of interindividual differences in pain and analgesia response shapes current approaches to assessment and treatment. Opportunities exist to improve pain care through increased understanding of how dynamic epigenomic remodeling shapes injury, illness, pain, and treatment response. Tightly regulated alterations of the DNA-histone chromatin complex enable cells to control transcription, replication, gene expression, and protein production. Pathological alterations to chromatin shape the ability of the cell to respond to physiologic and environmental cues leading to disease and reduced treatment effectiveness. This review provides an overview of critical epigenetic processes shaping pathology and pain, highlights current research support for the role of epigenomic modification in the development of chronic pain, and summarizes the therapeutic potential to alter epigenetic processes to improve health outcomes.

    Development of analgesic tolerance and withdrawal-induced pain enhancement present serious difficulties for the use of opioids for pain control. Although neuronal mechanisms to account for these phenomena have been sought for many decades, their bases remain unresolved. Within the past four years, a novel non-neuronal candidate has been uncovered that opposes acute opioid analgesia and contributes to development of opioid tolerance and tolerance-associated pain enhancement. This novel candidate is spinal cord glia. Glia are important contributors to the creation of enhanced pain states via the release of neuroexcitatory substances. New data suggest that glia also release neuroexcitatory substances in response to morphine, thereby opposing its effects. Controlling glial activation could therefore increase the clinical utility of analgesic drugs. PMID:16246435

    Full Text Available Abstract In a new mouse model for generalized pain syndrome, including fibromyalgia, which used intermittent cold stress (ICS, bilateral allodynia in the hindpaw was observed that lasted more than 12 days; thermal hyperalgesia lasted 15 days. During constant cold stress (CCS, mice showed only a transient allodynia. A female prevalence in ICS-induced allodynia was observed in gonadectomized but not in gonad intact mice. Systemic gabapentin showed complete anti-allodynic effects in the ICS model at the one-tenth dose for injury-induced neuropathic pain model, and central gabapentin showed long-lasting analgesia for 4 days in ICS, but not the injury model. These results suggest that the ICS model is useful for the study of generalized pain syndrome.

  7. Blockade of tolerance to morphine analgesia by cocaine.

    1989-07-01

    Tolerance to morphine analgesia was induced in male Sprague-Dawley rats by s.c. implantation of a morphine base pellet (75 mg) on the first and second day and determining the magnitude of tolerance 72 h after the first implant by s.c. injection of a test dose of morphine (5 mg/kg). Implantation of a cocaine hydrochloride pellet (25 mg), concurrently with morphine pellets or of a cocaine hydrochloride (50 mg) pellet after the development of tolerance, blocked both the development and expression of morphine analgesic tolerance. In morphine-pelleted animals pretreatment for 3 days with desipramine or zimelidine or phenoxybenzamine but not haloperidol produced no significant morphine tolerance. Pretreatment with a combination of desipramine and zimelidine, however, was as effective as cocaine in blocking morphine tolerance. Alpha-Methyl-p-tyrosine methyl ester counteracted the effect of cocaine in blocking morphine tolerance and potentiated the tolerance development. Blockade of morphine tolerance by cocaine was reinforced and facilitated by pretreatment with fenfluramine or p-chlorophenylalanine ethyl ester and to a lesser extent by clonidine and haloperidol. Acute administration of fenfluramine or zimelidine or a combination of desipramine and zimelidine or alpha-methyl-p-tyrosine methyl ester or p-chlorophenylalanine ethyl ester did not significantly affect morphine analgesia. The study suggests an important role of the concomitant depletion of both central noradrenaline and serotonin in the blockade of morphine tolerance by cocaine and stresses the importance of the counter-balancing functional relationship between these two neurotransmitters in the central nervous system.

    Full Text Available Background: Total knee arthroplasty represents one of the most painful surgeries. The aim of the study was to compare analgesia and adverse effects of intrathecal (IT ketorolac versus IT morphine, versus the combination of IT ketorolac and morphine. Materials and Methods: After ethical approval and patient consent, 80 patients undergoing knee arthroplasty were randomized to one of 4 groups. All groups received 15 mg IT bupivacaine plus IT test drug (2 ml. The control group (CG received saline as IT test drug. The morphine group (MG received IT 200 g morphine, the ketorolac group (KG IT 2 mg ketorolac and the morphine-ketorolac group (MKG 200 g morphine + 2 mg ketorolac as test drugs. Pain and adverse effects were evaluated. P < 0.05 was considered significant. Results: The MG and KG were similar in their times to time to first rescue analgesic (440 ± 38 min and 381 ± 44 min, respectively. Both groups were longer when compared to the CG (170 ± 13 min (P < 0.01. The MG and KG had lesser ketoprofen consumption compared to the CG (P < 0.05. The time to first rescue analgesic was longer to the MKG (926 ± 222 min (15 h compared to CG (P < 0.001 and to the MG and the KG (P < 0.01. MKG displayed lesser ketoprofen consumption compared to MG and KG (P < 0.05 and to the CG (P < 0.02. Conclusions: The data suggest a role for spinal ketorolac and morphine in orthopaedic surgery because this combination of agents provided 15 h of analgesia compared to 7 h after each drug alone, with no significant side-effects.

    Buprenorphine has long been classified as a mu analgesic, although its high affinity for other opioid receptor classes and the orphanin FQ/nociceptin ORL1 receptor may contribute to its other actions. The current studies confirmed a mu mechanism for buprenorphine analgesia, implicating several subsets of mu receptor splice variants. Buprenorphine analgesia depended on the expression of both exon 1-associated traditional full length 7 transmembrane (7TM) and exon 11-associated truncated 6 transmembrane (6TM) MOR-1 variants. In genetic models, disruption of delta, kappa1 or ORL1 receptors had no impact on buprenorphine analgesia, while loss of the traditional 7TM MOR-1 variants in an exon 1 knockout (KO) mouse markedly lowered buprenorphine analgesia. Loss of the truncated 6TM variants in an exon 11 KO mouse totally eliminated buprenorphine analgesia. In distinction to analgesia, the inhibition of gastrointestinal transit and stimulation of locomotor activity were independent of truncated 6TM variants. Restoring expression of a 6TM variant with a lentivirus rescued buprenorphine analgesia in an exon 11 KO mouse that still expressed the 7TM variants. Despite a potent and robust stimulation of (35) S-GTPγS binding in MOR-1 expressing CHO cells, buprenorphine failed to recruit β-arrestin-2 binding at doses as high as 10 µM. Buprenorphine was an antagonist in DOR-1 expressing cells and an inverse agonist in KOR-1 cells. Buprenorphine analgesia is complex and requires multiple mu receptor splice variant classes but other actions may involve alternative receptors. PMID:27223691

    Menthol, the cooling natural product of peppermint, is widely used in medicinal preparations for the relief of acute and inflammatory pain in sports injuries, arthritis, and other painful conditions. Menthol induces the sensation of cooling by activating TRPM8, an ion channel in cold-sensitive peripheral sensory neurons. Recent studies identified additional targets of menthol, including the irritant receptor, TRPA1, voltage-gated ion channels and neurotransmitter receptors. It remains unclear which of these targets contribute to menthol-induced analgesia, or to the irritating side effects associated with menthol therapy. Here, we use genetic and pharmacological approaches in mice to probe the role of TRPM8 in analgesia induced by L-menthol, the predominant analgesic menthol isomer in medicinal preparations. L-menthol effectively diminished pain behavior elicited by chemical stimuli (capsaicin, acrolein, acetic acid), noxious heat, and inflammation (complete Freund's adjuvant). Genetic deletion of TRPM8 completely abolished analgesia by L-menthol in all these models, although other analgesics (acetaminophen) remained effective. Loss of L-menthol-induced analgesia was recapitulated in mice treated with a selective TRPM8 inhibitor, AMG2850. Selective activation of TRPM8 with WS-12, a menthol derivative that we characterized as a specific TRPM8 agonist in cultured sensory neurons and in vivo, also induced TRPM8-dependent analgesia of acute and inflammatory pain. L-menthol- and WS-12-induced analgesia was blocked by naloxone, suggesting activation of endogenous opioid-dependent analgesic pathways. Our data show that TRPM8 is the principal mediator of menthol-induced analgesia of acute and inflammatory pain. In contrast to menthol, selective TRPM8 agonists may produce analgesia more effectively, with diminished side effects. PMID:23820004

    This randomized study was designed to compare the effectiveness of bilateral interpleural analgesia with lumbar epidural analgesia, on postoperative pain relief in upper abdominal surgery. The studied patients were randomely allocated into either interpleural group "IP" (n = 15) or epidural group "EP" (n = 15). In "IP" group, preanesthetic bilateral interpleural block was done using a mixture of bupivacaine 0.5% (0.8 mg/kg) and 2 mg morphine diluted to 50 ml saline for each side. In "EP" group, the same mixture-diluted in 20 ml saline-was injected in the epidural space (L2-3). The general anesthetic technique was the same in both groups. Hemodynamic, gasometric, verbal pain score (VPS) values and complications were compared in both techniques. Heart rate (HR) and mean arterial pressure (MAP) readings were in the accepted normal range in the perioperative period although significant lower readings were detected in "EP" group. No significant differences were displayed in blood gasometric variables between the two groups. There were considerable level of analgesia in both groups in the postoperative period although "EP" analgesia was superior to "IP". More pain free patients (9 versus 4) and significant lower consumption of nalbuphine were detected in "EP" group. The results of this study indicate that bilateral "IP" analgesia may offer a satisfactory analgesia for upper abdominal surgery when the use of other analgesic techniques may be contraindicated.

    Full Text Available Minimally invasive surgery with robotic assistance should elicit minimal pain. Regional analgesic techniques have shown excellent analgesia after thoracotomy. Thus the aim of this study was to compare thoracic epidural analgesia (TEA technique with paravertebral block (PVB technique in these patients with regard to quality of analgesia, complications, and haemodynamic and respiratory parameters. This was a prospective randomised study involving 36 patients undergoing elective robotic-assisted coronary artery bypass grafting (CABG. TEA or PVB were administered in these patients. The results revealed no significant differences with regard to demographics, haemodynamics, and arterial blood gases. Pulmonary functions were better maintained in PVB group postoperatively; however, this was statistically insignificant. The quality of analgesia was also comparable in both the groups. We conclude that PVB is a safe and effective technique for postoperative analgesia after robotic-assisted CABG and is comparable to TEA with regard to quality of analgesia.

    Full Text Available Background: Epidural anesthesia is regional anesthesia that blocks pain in a particular region of the body. This produces pain relief with minimal side effects. These medications may be used in combination with epinephrine, fentanyl, morphine, or clonidine to prolong the epidural’s effect or to stabilize the mother’s blood pressure. Objectives: This study was conducted to assess the fetomaternal outcome of epidural analgesia in labour. Methods: This study was descriptive case series study which was conducted in department of obstetrics and gynecology, GMERS medical college, Gandhinagar, Gujarat from January 2012 to December 2012. Pregnant women who received epidural analgesia during labour were involved in the study. The inclusion criteria were primi gravida patients who had gestational age of greater than 37 weeks (confirmed by ultrasound without any risk factors, in true labour (cervical dilatation >3 cm with regular uterine contraction and with vertex presentation. Results: Total number of patients was 80 with the mean age of 21.9±1.7 years. Mode of delivery was spontaneous vaginal in 46 patients (57.5%, forceps delivery in 4 patients (5%, ventouse in 14 patients (17.5% and caesarean section in 16 patients (20%. At one minute majority of the babies (n 63, 78.75% had Apgar score of more than 7, only 5 babies (6.25% had Apgar score less than 4, and 12 babies (15% had Apgar score between 4-7. At 5 minutes majority of the babies (n 74, 92.5% had Apgar score of more than 7, only one baby (1.25% had Apgar score less than 4, and 5 babies (6.25% had Apgar score between 4-7. Conclusion: Epidural anaesthesia provided excellent pain relief in majority of the patients. It can also be associated with increase duration of second stage of labour but not associated with fetal compromise in a properly managed patient. [Natl J Med Res 2013; 3(2.000: 184-186

    Full Text Available Neuraxial techniques of anaesthesia and analgesia are the current choice in obstetrics for efficacy and general low risk of major complications. Concern exists about neuraxial anaesthesia in patients with occult neural tube defects, regarding both labour analgesia and anaesthesia for Caesarean section. Recently, remifentanil infusion has been proposed as an analgesic technique alternative to lumbar epidural, especially when epidural analgesia appears to be contraindicated. Here, we discuss the case of a pregnant woman attending at our institution with occult, symptomatic spinal dysraphism who requested labour analgesia. She was selected for remifentanil intravenous infusion for labour pain and then underwent urgent operative delivery with spinal anaesthesia with no complications.

    Compendio El Reclutamiento y la Retención (R&R) de participantes es fundamental para el éxito de estudios y para el desarrollo de intervenciones preventivas. El R&R de participantes determina la validez y efectividad de estos programas. En este trabajo examinamos algunos de los factores que facilitan y dificultan el R&R en los proyectos preventivos y ofrecemos algunas alternativas para mejorar los índices de R&R. Realizamos dos estudios, en el primero administramos el Instrumento de Informatión, Motivatión y Conductas-Español (IIMC-E) a un grupo de 26 parejas heterosexuales (52 participantes). En el segundo, entrevistamos a 5 parejas VIH discordantes (10 participantes). Encontramos que el 75% de los/las participantes indicó que su trabajo era una de las principales barreras que dificultan la asistencia a las actividades. Otras barreras son las responsabilidades laborales y familiares. Encontramos que la principal barrera fue el miedo a la revelación del estado serlógico. Los principales facilitadores del R&R son la coordinación adecuada y el seguimiento telefónico ofrecido por parte del personal del proyecto. Concluimos que en el desarrollo e implantación de programas de prevención el investigador/a debe tomar en cuenta la adaptación de aspectos logísticos como la disponibilidad y las necesidades particulares de los/las participantes.

    Full Text Available Background: Postoperative pain after breast cancer surgery is not uncommon. Narcotic based analgesia is commonly used for postoperative pain management. However, the side-effects and complications of systemic narcotics is a significant disadvantage. Different locoregional anesthetic techniques have been tried including, single and multiple levels paravertebral block (PVB, which seems to have a significant reduction in immediate postoperative pain with fewer side-effects. The aim of this study was to compare unilateral multiple level PVB versus morphine patient-controlled analgesia (PCA for pain relief after breast cancer surgery with unilateral lumpectomy and axillary lymph nodes dissection. Materials and Methods: Forty patients scheduled for breast cancer surgery were randomized to receive either preoperative unilateral multiple injections PVB at five thoracic dermatomes (group P, 20 patients or postoperative intravenous PCA with morphine (group M, 20 patients for postoperative pain control. Numerical pain scale, mean arterial pressure, heart rate, Time to first analgesic demand, 24-h morphine consumption side-effects and length of hospital stay were recorded. Results: PVB resulted in a significantly more postoperative analgesia, maintained hemodynamic, more significant reduction in nausea and vomiting, and shorter hospital stay compared with PCA patients. Conclusion: Multiple levels PVB is an effective regional anesthetic technique for postoperative pain management, it provides superior analgesia with less narcotics consumption, and fewer side-effects compared with PCA morphine for patients with breast cancer who undergo unilateral lumpectomy, with axillary lymph nodes dissection.

    Somatosensory event-related potentials (SERPs) to painful electric standard stimuli under an odd-ball paradigm were analyzed in 12 high hypnotizable (HH), 12 medium hypnotizable (MH), and 12 low hypnotizable (LH) subjects during waking, hypnosis, and a cued eyes-open posthypnotic condition. In each of these conditions subjects were suggested to produce an obstructive imagery of stimulus perception as a treatment for pain reduction. A No-Analgesia treatment served as a control in waking and hypnosis conditions. The subjects were required to count the number of delivered target stimuli. HH subjects experienced significant pain and distress reductions during posthypnotic analgesia as compared to hypnotic analgesia and between these two analgesic conditions as compared to the two control conditions. Outside of hypnosis, these subjects remembered less pain and distress levels than they reported during hypnotic and posthypnotic analgesia treatments. In contrast, for waking-analgesia treatment, HH subjects remembered similar pain and distress levels to those they reported concurrently with the stimulation. HH subjects, during hypnotic and posthypnotic analgesia treatments, detected a smaller number of target stimuli and displayed a significant amplitude reduction of the midline frontal and central N140 and P200 SERP components. No significant SERP differences were observed for these subjects between treatments in waking condition and between hypnotic and posthypnotic analgesic treatments. For the MH and LH subjects no significant N140 and P200 amplitude changes were observed among analgesic conditions as compared to control conditions. These amplitude findings are seen as indicating that hypnotic analgesia can affect earlier and later stages of stimulus processing. PMID:18023535

    The provision of epidural analgesia for postoperative pain control offers many patient benefits and has become commonplace on many nursing units. Since nurses are responsible for the day-to-day management of patients receiving epidural analgesia, their knowledge, attitudes, and practices regarding this technique are pivotal to its success. Therefore, the purpose of the present descriptive study was to examine the knowledge base, attitudes, and clinical practice of registered nurses (N = 85) regarding postoperative epidural analgesia as managed by an acute pain service (APS). Information was obtained from a survey distributed via a convenience sample to all nurses working on 6 units in a large military teaching facility. We developed the "Epidural Knowledge and Attitude Survey" using the nursing literature on epidural analgesia. The survey consisted of a demographics section, true/false (T/F) questions, multiple choice (M/C) questions, an attitude section, and a comment section. These sections addressed the nurses' knowledge, attitudes, and practices in regard to epidural pharmacology, management, and adverse effects, as well as their general satisfaction with the APS of their facility. Data were analyzed statistically using means, standard deviations, percentages, forward step-wise linear regression, the Fisher-Irwin (exact) test, the chi 2 test, and analysis of variance with Bonferroni multiple comparisons. A P value of attitude section illustrated that 73% of nurses had "positive" attitudes toward epidural analgesia. Correct management of patients receiving epidural analgesia was being practiced by 77% of nurses. The satisfaction with the APS at this facility was 32% "very satisfied" and 62% "somewhat satisfied." The demographic characteristics that best predicted a higher score on the knowledge portion of the survey were greater years of practice as a nurse and receipt of pain education in nursing training. Nurses who had received inservice education about

    Full Text Available Purpose. Transversus abdominis plane (TAP blocks have been shown to reduce pain and opioid requirements after abdominal surgery. The aim of the present case series was to demonstrate the use of TAP catheter injections of bupivacaine after major abdominal surgery. Methods. Fifteen patients scheduled for open colonic resection surgery were included. After induction of anesthesia, bilateral TAP catheters were placed, and all patients received a bolus dose of 20 mL bupivacaine 2.5 mg/mL with epinephrine 5 μg/mL through each catheter. Additional bolus doses were injected bilaterally 12, 24, and 36 hrs after the first injections. Supplemental pain treatment consisted of paracetamol, ibuprofen, and gabapentin. Intravenous morphine was used as rescue analgesic. Postoperative pain was rated on a numeric rating scale (NRS, 0–10 at regular predefined intervals after surgery, and consumption of intravenous morphine was recorded. Results. The TAP catheters were placed without any technical difficulties. NRS scores were ≤3 at rest and ≤5 during cough at 4, 8, 12, 18, 24, and 36 hrs after surgery. Cumulative consumption of intravenous morphine was 28 (23–48 mg (median, IQR within the first 48 postoperative hours. Conclusion. TAP catheter bolus injections can be used to prolong analgesia after major abdominal surgery.

    Full Text Available In daily life, dental treatments are often related with oral pain sensation which needs anesthesia procedures. Sometimes local anesthetics can not be used because patients have hypersensitive reaction or systemic diseases which may lead to complications. Stimulating acupoint, such as Hegu activates hypothalamus and pituitary gland to release endogenous opioid peptide substances that reduce pain sensitivity. The aim of the study was to determine Hegu acupoint stimulation effect on the pain sensitivity reduction in maxillary central incisor gingiva. The laboratory experimental research was conducted on 12 healthy male Wistar rats (3 months old, weights 150–200 grams. All rat samples received the same treatments and adapted within 1 month. The research was done in pre and post test control group design. 40-Volt electro-stimulation was done once on the maxillary central incisor gingiva prior to the bilateral Hegu acupoint stimulation, then followed by 3 times electro-stimulation with 3 minutes intervals. The pain scores were obtained based on the samples’ contraction in each electro-stimulation. The responses were categorized into 5 pain scores and statistically analyzed using Wilcoxon Test. The results showed that Hegu acupoint stimulation lowered the pain scores significantly (p < 0.05. Hegu acupoint stimulation could reduce the pain sensitivity in maxillary central incisor gingiva. Therefore, the use of acupuncture analgesia in dental pain management can be considered in the future.

    Full Text Available Fundament: One of the most important aims of modern surgery is the recovery of the ill patients and heir integration to society. Sometimes, this wish has its limitations because of the persistence of pain after surgery. The development of an effective analgesic for after surgery pain is therefore a priority in modern medicine. Objective: To characterize the results obtained with the application of a preventive analgesic by infiltrating without limitations of the use of any other analgesic if necessary. Method: Prospective-descriptive study in a series of 30 patients assisted at the Orthopaedic Service of the ¨Dr. Gustavo Aldereguía Lima¨ Hospital from Cienfuegos province in the period that covers September 2004- march 2005. Anaesthetic infiltration in the surgical area was applied once the surgery was ended . Bupivacaine 0,125 % in a volume of 20 ml and 2 drops of epinephrine without avoiding the use of any other analgesic. Results: a group of 13 patients presented pain in the first 24-48 hours after surgery followed by another group of 9 patients who alleviated pain in the period between 12 and 23 hours after surgery. Conclusions: In this series of patients it was shown the benefits of anaesthetic infiltration in the surgical area with analgesic purposes, since it causes pain alleviation in a period greater than 24 hours. Bupivacaine shows good results since it causes after surgery analgesia and the early application in the rehabilitation of a great number of patients.

    AIM: To present our experience using intravenous sedoanalgesia for percutaneous biliary drainage. MATERIALS AND METHODS: This study comprised 100 patients, all of whom were continuously monitored [electrocardiogram (ECG), blood pressure, pulse oxymetry] and received an initial dose of 2 mg midazolam followed by 0.02 mg fentanyl. Before every anticipated painful procedure, a maintenance dose of 0.01 mg fentanyl was administered. If the procedure continued and the patient became aware, another 1 mg midazolam was given. This was repeated if patients felt pain. A total dose of 0.08 mg fentanyl and 7 mg midazolam was never exceeded. Immediately after the procedure, the nurse was asked to evaluate patients' pain score. The patients were asked 3 h later to complete a visual 10-degree pain score scale. RESULTS: The average dose of fentanyl and midazolam was 0.042 mg (0.03-0.08 mg) and 4.28 mg (2-7 mg), respectively. Only one patient recorded the procedure as painful. The scores given by the attending nurse (1-7 points, mean 2.9) correlated well with those given by the patients (1-6 points, mean 2.72). No complications were noted. CONCLUSION: According to our experience, interventional radiologists practising biliary procedures can administer low doses of midazolam and minimize the doses of fentanyl, without loss of adequate sedation and analgesia.

    A double-blind, placebo-controlled, parallel-group study was performed to compare the analgesic activity of the combination of 650 mg acetaminophen plus 60 mg phenyltoloxamine citrate with that of 650 mg acetaminophen alone. Two hundred female inpatients who had severe pain associated with a recent episiotomy procedure were randomly assigned to receive a single dose of one of the two active treatments or a placebo. Analgesia was assessed over a 6-hour period. Treatments were compared on the basis of standard subjective scales for pain intensity and relief, a number of derived variables based on these data and two global measures. For essentially all measures, the two active treatments were significantly superior to the placebo control. The combination was significantly superior to acetaminophen alone for all analgesic measures including SPID, TOTAL, and global ratings. The results of this study demonstrate that 60 mg phenyltoloxamine produces significant augmentation of the analgesic activity of 650 mg acetaminophen in postepisiotomy pain. PMID:2569485

    The PhysioDoloris™ analgesia monitor assesses nociception effects on the autonomic nervous system by analyzing changes in heart rate variability (HRV). This non-invasive device analyses ECG signals and determines the analgesia nociception index (ANI), allowing for quantitative assessment of the analgesia/nociception balance in anesthetized patients. Ketamine, an analgesic adjuvant with sympathomimetic properties, has been shown to improve perioperative pain management. The purpose of this pilot study was to evaluate whether low-dose ketamine, due to its intrinsic effect on the sino-atrial node, affects HRV and, therefore, interferes with ANI measurements. This pilot study included 20 women undergoing abdominal hysterectomies. Anesthesia and analgesia were maintained with sevoflurane and fentanyl respectively, in a standardized manner. Five minutes after intubation, 0.5 μg kg(-1) of intravenous (i.v.) ketamine was administered. ANI, bispectral index (BIS), heart rate and blood pressure were recorded from the induction of anesthesia until 5 min after skin incision. There was not any significant decrease in mean (±SD) ANI values after intubation (2.11±20.11, p=0.35) or i.v. ketamine administration (1.31±15.26, p=0.28). The mean (±SD) reduction in ANI values after skin incision was statistically significant (13.65±15.44, p=0.01), which is consistent with increased nociception. A single i.v. bolus of 0.5 μg kg(-1) ketamine did not influence the ANI values of 20 women under standardized general anesthesia conditions and absent noxious stimulation. These results suggest that the ANI derived from the PhysioDoloris™ analgesia monitor is feasible under such clinical conditions. PMID:25062948

    The vast research have demonstrated that the acupuncture analgesia is effected through a physiological mechanism brought about by the nervous system, particularly the central nervous system. We combined the acupuncture effects and theory of channels and collaterals with the new advance of pain neurophysiology, and centred attention on nucleus raphe magnus (NRM), that is one of the origins of the important descending inhibitory pathways of the intrinsic analgesic systems in brain. The unit discharges of NRM neurons and their nociceptors/ph responses were recorded extracellularly with glass microelectrode at 1495 neurons on 634 wastar rats. The modulation of cerebral cortex, the head of N. caudatum (NCa), N. Accumbens (N. Ac), N lateral habenular (NHa) and Periaquaeductal gray matter (PAG) on NRM and their role in acupuncture analgesia were studied by central locational stimulation, lesion and microinjection. The result were as follows: 1. The most NRM neurons could respond to noxious stimulation of tail tip with increasing or decreasing firing rate. Electroacupuncture (EA) at "Zusanli" could activate the NRM neuron, increasing discharges, and inhibit their nociceptive responses, producing analgesia. 2. The activity of NRM neuron was modulated by PAG, NAc, and NCa. Stimulation at one of them can activate neuron of NRM, increasing firing rate, and induce analgesia. When the lesion or microinjection naloxone were made in PAG, NAc or NCa, EA analgesia could be weakened or lost, even the nociceptive responses might be increased. It is suggest that the nuclei participated in EA analgesia with their endogenous opiate like substance, and were playing an important role. It is also indicated that the electroacupuncture was used on the patients with some nuclei lesion or pathological changes should be careful to avoid making patients feel more painful. 3. Somatosensory area II (Sm II) of cerebral cortex participated in EA analgesia. The analgesic effects of EA at "Zusanli

    Full Text Available Remifentanil with appropriate pharmacological properties seems to be an ideal alternative to epidural analgesia during labour. A retrospective cohort study was undertaken to assess the efficacy and safety of remifentanil intravenous patient-controlled analgesia (IVPCA compared with epidural analgesia. Medical records of 370 primiparas who received remifentanil IVPCA or epidural analgesia were reviewed. Pain and sedation scores, overall satisfaction, the extent of pain control, maternal side effects and neonatal outcome as primary observational indicators were collected. There was a significant decline of pain scores in both groups. Pain reduction was greater in the epidural group throughout the whole study period (0 ∼ 180 min (P < 0.0001, and pain scores in the remifentanil group showed an increasing trend one hour later. The remifentanil group had a lower SpO2 (P < 0.0001 and a higher sedation score (P < 0.0001 within 30 min after treatment. The epidural group had a higher overall satisfaction score (3.8 ± 0.4 vs. 3.7 ± 0.6, P = 0.007 and pain relief score (2.9 ± 0.3 vs. 2.8 ± 0.4, P < 0.0001 compared with the remifentanil group. There was no significant difference on side effects between the two groups, except that a higher rate of dizziness (1% vs. 21.8%, P < 0.0001 was observed during remifentanil analgesia. And logistic regression analysis demonstrated that nausea, vomiting were associated with oxytocin usage and instrumental delivery, and dizziness was associated to the type and duration of analgesia. Neonatal outcomes such as Apgar scores and umbilical-cord blood gas analysis were within the normal range, but umbilical pH and base excess of neonatus in the remifentanil group were significantly lower. Remifentanil IVPCA provides poorer efficacy on labor analgesia than epidural analgesia, with more sedation on parturients and a trend of newborn acidosis. Despite these adverse effects, remifentanil IVPCA can still be an alternative

    Multimodal analgesia is promoted as the best practice pain management for invasive animal research procedures. Universal acceptance and incorporation of multimodal analgesia requires assessing potential effects on study outcome. The focus of this study was to assess effects on embryo survival after multimodal analgesia comprising an opioid and nonsteroidal antiinflammatory drug (NSAID) compared with opioid-only analgesia during embryo transfer procedures in transgenic mouse production. Mice were assigned to receive either carprofen (5 mg/kg) with buprenorphine (0.1 mg/kg; CB) or vehicle with buprenorphine (0.1 mg/kg; VB) in a prospective, double-blinded placebo controlled clinical trial. Data were analyzed in surgical sets of 1 to 3 female mice receiving embryos chimeric for a shared targeted embryonic stem-cell clone and host blastocyst cells. A total of 99 surgical sets were analyzed, comprising 199 Crl:CD1 female mice and their 996 offspring. Neither yield (pups weaned per embryo implanted in the surgical set) nor birth rate (average number of pups weaned per dam in the set) differed significantly between the CB and VB conditions. Multimodal opioid-NSAID analgesia appears to have no significant positive or negative effect on the success of producing novel lines of transgenic mice by blastocyst transfer. PMID:21838973

    The objective is to study the effects of flurbiprofen axetil (FA) with fentanyl together in postoperative controlled intravenous analgesia (PCIA) on pain intensity, cytokine levels in peripheral blood and adverse reactions of thoracotomy patients. Fifty thoracotomy patients were divided into a FA and a control group, each with 25 cases. Postoperative analgesia was administered in the two groups using PCIA. The pressing times of analgesia pump, the visual analog scale (VAS) scores during resting and coughing at 2, 6, 24, 48, 72 h after surgery and the incidence of adverse drug reactions were recorded. Levels of IL-1β, IL-6, IL-8, IL-2, and TNF-α in peripheral blood were determined before the administration of FA (T0), and at 24 h (T1), 48 h (T2), 72 h (T3) after surgery. The analgesia pump pressing times in the FA group was less than that of the control group. The VAS scores during resting and coughing at 2, 6, 24, 48, 72 h after surgery, were statistically less than those of control group. The incidence rate of nausea and vomiting was insignificantly different between the two groups. Administration of FA together with PCIA in thoracotomy patients can improve postoperative analgesia.

    Full Text Available ABSTRACT BACKGROUND AND OBJECTIVES: Combined spinal-epidural (CSE has become an increasingly popular alternative to traditional labour epidural due to its rapid onset and reliable analgesia provided. This was a prospective, convenient sampling study to determine the effects of CSE analgesia on labour outcome. METHODS: One hundred and ten healthy primigravida parturients with a singleton pregnancy of ≥37 weeks gestation and in the active phase of labour were studied. They were enrolled to the CSE (n = 55 or Non-CSE (n = 55 group based on whether they consented to CSE analgesia. Non-CSE parturients were offered other methods of labour analgesia. The duration of the first and second stage of labour, rate of instrumental vaginal delivery and emergency cesarean section, and Apgar scores were compared. RESULTS: The mean duration of the first and second stage of labour was not significantly different between both groups. Instrumental delivery rates between the groups were not significantly different (CSE group, 11% versus Non-CSE group, 16%. The slightly higher incidence of cesarean section in the CSE group (16% versus 15% in the Non-CSE group was not statistically significant. Neonatal outcome in terms of Apgar score of less than 7 at 1 and 5 min was similar in both groups. CONCLUSION: There were no significant differences in the duration of labour, rate of instrumental vaginal delivery and emergency cesarean section, and neonatal outcome in parturients who received compared to those who did not receive CSE for labour analgesia.

    Full Text Available Caudal epidural analgesia with bupivacaine is very popular in paediatric anaesthesia for providing intra- and postoperative analgesia. Several adjuvants have been used to prolong the action of bupivacaine. We evaluated the efficacy of clonidine added to bupivacaine in prolonging the analgesia produced by caudal bupivacaine in children undergoing sub-umbilical surgery. One hundred children, age one to three years, undergoing sub-umbilical surgery, were prospectively randomized to one of two groups: caudal analgesia with 1 ml/kg of 0.25% bupivacaine in normal saline (Group A or caudal analgesia with 1 ml/kg of 0.25% bupivacaine with 1 μg/kg of clonidine in normal saline (Group B. Post-operative pain was assessed for 24 hours using the FLACC scale. The mean duration of analgesia was significantly longer in Group B (593.4 ± 423.3 min than in Group A (288.7 ± 259.1 min; P < 0.05. The pain score assessed using FLACC scale was compared between the two groups, and children in Group B had lower pain scores, which was statistically significant. The requirement of rescue medicine was lesser in Group B. Clonidine in a dose of 1 μg/kg added to 0.25% bupivacaine for caudal analgesia, during sub-umbilical surgeries, prolongs the duration of analgesia of bupivacaine, without any side effects.

    Full Text Available Background: Tapentadol is a relatively new analgesic. We decided to compare it with tramadol for their various effects after cardiac surgery. Setting: A study in a tertiary care hospital. Materials and Methods: Sixty adults undergoing cardiac surgery were divided into 2 groups of 30 each by computerized random allotment (Group X = tapentadol 50 mg oral and Group Y = tramadol 100 mg oral. Informed Consent and Institutional Ethics Committee approval were obtained. The patients were given either drug X or drug Y after extubation in this single blinded study, wherein the data collectors and analyzers were blinded to the study. All patients received oral paracetamol qds and either drug X or drug Y tds. The pain score was noted on a Visual Analog Scale before each drug dose, 3 h later and on coughing. Heart rate, respiratory rate, and blood pressure were recorded before the drug dose and 3 h later. Postoperative nausea or vomiting (PONV, temperature, and modified Glasgow Coma Scale readings were recorded. The above readings were obtained for 6 doses (up to 48 h after extubation. Statistics: t-test, Pearson Chi-square test, Fisher exact test, and Mantel-Haenszel test were used for statistics. Results: Tapentadol group patients had significantly better analgesia 3 h after the drug and "on coughing" than tramadol group. The difference in their effects on blood creatinine levels, temperature, hemodynamics, oxygen saturation, and respiratory rate were not clinically significant. Tapentadol produced lesser drowsiness and lesser vomiting than tramadol. Conclusions: Tapentadol, due to its norepinephrine reuptake inhibition properties, in addition to mu agonist, is a better analgesic than tramadol and has lesser PONV.

  1. Effects of regional analgesia on stress responses to pediatric surgery.

    Science.gov (United States)

    Wolf, Andrew R

    2012-01-01

    Invasive surgery induces a combination of local response to tissue injury and generalized activation of systemic metabolic and hormonal pathways via afferent nerve pathways and the central nervous system. The local inflammatory responses and the parallel neurohumoral responses are not isolated but linked through complex signaling networks, some of which remain poorly understood. The magnitude of the response is broadly related to the site of injury (greater in regions with visceral pain afferents such as abdomen and thorax) and the extent of the trauma. The changes include alterations in metabolic, hormonal, inflammatory, and immune systems that can be collectively termed the stress response. Integral to the stress responses are the effects of nociceptive afferent stimuli on systemic and pulmonary vascular resistance, heart rate, and blood pressure, which are a combination of efferent autonomic response and catecholamine release via the adrenal medulla. Therefore, pain responses, cardiovascular responses, and stress responses need to be considered as different aspects of a combined bodily reaction to surgery and trauma. It is important at the outset to understand that not all components of the stress response are suppressed together and that this is important when discussing different analgesic modalities (i.e. opioids vs regional anesthesia). For example, in terms of the use of fentanyl in the infant, the dose required to provide analgesia (1-5 mcg·kg(-1)) is less than that required for hemodynamic stability in response to stimuli (5-10 mcg·kg(-1)) (1) and that this in turn is less than that required to suppress most aspects of the stress response (25-50 mcg·kg(-1)) (2). In contrast to this considerable dose dependency, central local anesthetic blocks allow blockade of the afferent and efferent sympathetic pathways at relatively low doses resulting in profound suppression of hemodynamic and stress responses to surgery.

    subjective: The effect of 4~5 Hz electroacupuncture (EA) on alterations of both met-enkephalin (MEK) and dynorphin (Dyn) in the patient plasma or mouse spinal cord and its relation with analgesic effect were studied. Methods: In acupuncture clinic 10 patients with acute pain were treated with 4 Hz EA at Zusanli(ST 36) and/or Hegu(LI 4) acupoints for 30 min. 20 BALB/C mice were randomly divided into 2 groups: a. EA group(n=10), treated with 4~5 Hz EA at bilateral "Zusanli"(ST 36) for 15 min; b. control group(n=10) treated with no EA, but also restrained for 15 min. Before and after EA or restraining acupoints, the pain threshold of the patients or mice was detected. 10 μI of the patient plasma before and after EA and each mouse spinal cord suspension, of the 2 groups were blotted onto nitrocellulose membrane (NCM) respectively. The protein dot blot signals were detected by immunoreactivity (IR) and using Shimadu TLC Scanner and analyzed statistically. Results: The results showed that an increase in patient plasma MEK-IR or Dyn-IR and a decrease in mouse spinal MEK-IR or Dyn-IR could be detected, and the alteration of plasma or spinal MEK-IR was more significant than that of plasma or spinal Dyn-IR. There was a positive correlation in alteration between plasma or spinal MEK-IR and plasma or spinal Dyn-IR with respective parallel levels in individuals. The increased plasma MEK-IR or the decreased spinal MEK-IR was positively or negatively correlated with the analgesic effect, while the correlation between plasma or spinal Dyn-IR and analgesic effect was insignificant. Conclusion: The results suggest that under lower frequency EA the met-enkephalin may play an important role in analgesia.

    Full Text Available A function of the endogenous analgesic system is to prevent recuperative behaviors generated by tissue damage, thus preventing the emission of species-specific defensive behaviors. Activation of intrinsic nociception is fundamental for the maintenance of the behavioral strategy adopted. Tonic immobility (TI is an inborn defensive behavior characterized by a temporary state of profound and reversible motor inhibition elicited by some forms of physical restraint. We studied the effect of TI behavior on nociception produced by the formalin and hot-plate tests in guinea pigs. The induction of TI produced a significant decrease in the number of flinches (18 ± 6 and 2 ± 1 in phases 1 and 2 and lickings (6 ± 2 and 1 ± 1 in phases 1 and 2 in the formalin test when compared with control (75 ± 13 and 22 ± 6 flinches in phases 1 and 2; 28 ± 7 and 17 ± 7 lickings in phases 1 and 2. In the hot-plate test our results also showed antinociceptive effects of TI, with an increase in the index of analgesia 30 and 45 min after the induction of TI (0.67 ± 0.1 and 0.53 ± 0.13, respectively when compared with control (-0.10 ± 0.08 at 30 min and -0.09 ± 0.09 at 45 min. These effects were reversed by pretreatment with naloxone (1 mg/kg, ip, suggesting that the hypoalgesia observed after induction of TI behavior, as evaluated by the algesimetric formalin and hot-plate tests, is due to activation of endogenous analgesic mechanisms involving opioid synapses.

    Objective: to assess the analgesic efficacy of subcutaneous lidocaine and multimodal analgesia for chest tube removal following heart surgery. Methods: sixty volunteers were randomly allocated in two groups; 30 participants in the experimental group were given 1% subcutaneous lidocaine, and 30 controls were given a multimodal analgesia regime comprising systemic anti-inflammatory agents and opioids. The intensity and quality of pain and trait and state anxiety were assessed. The association between independent variables and final outcome was assessed by means of the Chi-squared test with Yates' correction and Fisher's exact test. Results: the groups did not exhibit significant difference with respect to the intensity of pain upon chest tube removal (p= 0.47). The most frequent descriptors of pain reported by the participants were pressing, sharp, pricking, burning and unbearable. Conclusion: the present study suggests that the analgesic effect of the subcutaneous administration of 1% lidocaine combined with multimodal analgesia is most efficacious. PMID:26625989

    2013-01-01

    Full Text Available We discuss the emerging translational tools for the study of acupuncture analgesia with a focus on psychophysical methods. The gap between animal mechanistic studies and human clinical trials of acupuncture analgesia calls for effective translational tools that bridge neurophysiological data with meaningful clinical outcomes. Temporal summation (TS and conditioned pain modulation (CPM are two promising tools yet to be widely utilized. These psychophysical measures capture the state of the ascending facilitation and the descending inhibition of nociceptive transmission, respectively. We review the basic concepts and current methodologies underlying these measures in clinical pain research, and illustrate their application to research on acupuncture analgesia. Finally, we highlight the strengths and limitations of these research methods and make recommendations on future directions. The appropriate addition of TS and CPM to our current research armamentarium will facilitate our efforts to elucidate the central analgesic mechanisms of acupuncture in clinical populations.

    Full Text Available BACKGROUND: This study aims to identify that intrathecal (i.t. injection of dexmedetomidine (Dex and ropivacaine (Ropi induces synergistic analgesia on chronic inflammatory pain and is accompanied with corresponding "neuron-astrocytic" alterations. METHODS: Male, adult Sprague-Dawley rats were randomly divided into sham, control and i.t. medication groups. The analgesia profiles of i.t. Dex, Ropi, and their combination detected by Hargreaves heat test were investigated on the subcutaneous (s.c. injection of complete Freund adjuvant (CFA induced chronic pain in rat and their synergistic analgesia was confirmed by using isobolographic analysis. During consecutive daily administration, pain behavior was daily recorded, and immunohistochemical staining was applied to investigate the number of Fos-immunoreactive (Fos-ir neurons on hour 2 and day 1, 3 and 7, and the expression of glial fibrillary acidic protein (GFAP within the spinal dorsal horn (SDH on day 1, 3, 5 and 7 after s.c. injection of CFA, respectively, and then Western blot to examine spinal GFAP and β-actin levels on day 3 and 7. RESULTS: i.t. Dex or Ropi displayed a short-term analgesia in a dose-dependent manner, and consecutive daily administrations of their combination showed synergistic analgesia and remarkably down-regulated neuronal and astrocytic activations indicated by decreases in the number of Fos-ir neurons and the GFAP expression within the SDH, respectively. CONCLUSION: i.t. co-delivery of Dex and Ropi shows synergistic analgesia on the chronic inflammatory pain, in which spinal "neuron-astrocytic activation" mechanism may play an important role.

Objetivou-se com este trabalho fazer uma breve revisão sobre as aplicações clínicas e os efeitos fisiológicos da acupuntura nos mecanismos da dor, bem como demonstrar os principais pontos de acupuntura utilizados para analgesia em animais. A pesquisa foi realizada em bases de dados eletrônicas por palavra-chave, durante o período de março a dezembro de 2008.Pain is a protective response of the body to harmful stimulus, which results in undesirable effects if not controlled. Analgesia can be achieved with the use of different types of drugs. However, these drugs can cause adverse effects according to species and patient physical condition. Acupuncture has been proved to be an effective analgesic adjuvant, by the capacity to decrease the amount of drug used for pain control, rarely contra-indicated. The aim of this paper was to review the physiological effects of acupuncture on pain mechanisms, and demonstrate the main acupoints used for animal analgesia. The search was done in electronic search database using key words, in 2008.

    Background Although there are various methods for painless delivery such as using entonox gas, most of the people are unfamiliar or concerned about it yet. Objectives The purpose of this study was to assess maternal expectations and experience of labor analgesia with nitrous oxide. Patients and Methods In a clinical trial study, 98 pregnant women in active phase of delivery were studied randomly in two groups (intervention group = 49, control group = 49) after obtaining written consent. Efficacy, experience satisfaction, and also expectation of pregnant women about entonox gas in two groups were compared, likewise in intervention group before and after using entonox gas. Results Most of the pregnant women receiving entonox gas had less labor pain (91.8%), and were satisfied with it (98%). The severity of pain in the most of entonox user was moderate level (46.94%), while for the control group it was severe (55.10%) which was significant, 40.82% of the mother in entonox group had a severe pain and 10.20% had a very severe pain, whereas in the control group (55.10%) of the mother had a severe pain and 26.53% of the had very severe pain (P = 0.004). efficacy of labor pain was in moderate level in most cases. 49% of pregnant women receiving gas described their experience as a good and excellent. 80.9% indicated that they will request the mentioned painless method in the future. The amount of suffering from gas side effects was mild in most patients of intervention group (63%). Expectations of the majority of pregnant women in intervention group (before receiving gas) and control group for painless delivery were weak (65.3%, 40.9%). The percentage of positive expectations had increased after receiving entonox gas (P = 0.01). There was a difference between the expectations of intervention group receiving entonox gas and control group (P = 0.001). Positive expectations were more in intervention group than the control group. Most differences of expectations in intervention

    Full Text Available Background and Aims: Caudal epidural block is the most commonly used neuraxial block in children. Morphine has been used as a caudal additive for more than three decades. The aim of our study was to evaluate the efficacy and duration of analgesia of three different doses of caudal epidural morphine (CEM, and to find out the incidence of side effects. Material and Methods: This study was conducted on 75 patients of American Society of Anesthesiologists grades I and II, aged 2-12 years, undergoing lower abdominal and urogenital surgeries. Patients were randomly allocated to one of the three groups according to the dose of morphine. Group I received 30 μg/kg, group II 50 μg/kg, and group III 70 μg/kg. Heart rate, blood pressure, oxygen saturation, electrocardiogram, pain score, sedation score, duration of analgesia, and side-effects were noted. Results: The mean duration of analgesia was 8.63 h in group I, 13.36 h in group II and 19.19 h in group III. Respiratory depression was noted in three patients in group III. One patient in group I had itching. One patient each in groups I, II, and III had nausea/vomiting. Conclusion: CEM significantly prolongs the duration of analgesia, though with a higher dose the risk of respiratory depression should always be kept in mind.

    Full Text Available This review will introduce the concept of toll-like receptor (TLR–mediated glial activation as central to all of the following: neuropathic pain, compromised acute opioid analgesia, and unwanted opioid side effects (tolerance, dependence, and reward. Attenuation of glial activation has previously been demonstrated both to alleviate exaggerated pain states induced by experimental pain models and to reduce the development of opioid tolerance. Here we demonstrate that selective acute antagonism of TLR4 results in reversal of neuropathic pain as well as potentiation of opioid analgesia. Attenuating central nervous system glial activation was also found to reduce the development of opioid dependence, and opioid reward at a behavioral (conditioned place preference and neurochemical (nucleus accumbens microdialysis of morphine-induced elevations in dopamine level of analysis. Moreover, a novel antagonism of TLR4 by (+- and (˗-isomer opioid antagonists has now been characterized, and both antiallodynic and morphine analgesia potentiating activity shown. Opioid agonists were found to also possess TLR4 agonistic activity, predictive of glial activation. Targeting glial activation is a novel and as yet clinically unexploited method for treatment of neuropathic pain. Moreover, these data indicate that attenuation of glial activation, by general or selective TLR antagonistic mechanisms, may also be a clinical method for separating the beneficial (analgesia and unwanted (tolerance, dependence, and reward actions of opioids, thereby improving the safety and efficacy of their use.

    Placebo analgesia involves the endogenous opioid system, as administration of the opioid antagonist naloxone decreases placebo analgesia. To investigate the opioidergic mechanisms that underlie placebo analgesia, we combined naloxone administration with functional magnetic resonance imaging. Naloxone reduced both behavioral and neural placebo effects as well as placebo-induced responses in pain-modulatory cortical structures, such as the rostral anterior cingulate cortex (rACC). In a brainstem-specific analysis, we observed a similar naloxone modulation of placebo-induced responses in key structures of the descending pain control system, including the hypothalamus, the periaqueductal gray (PAG), and the rostral ventromedial medulla (RVM). Most importantly, naloxone abolished placebo-induced coupling between rACC and PAG, which predicted both neural and behavioral placebo effects as well as activation of the RVM. These findings show that opioidergic signaling in pain-modulating areas and the projections to downstream effectors of the descending pain control system are crucially important for placebo analgesia.

    Placebo analgesia is one of the most striking examples of the cognitive modulation of pain perception and the underlying mechanisms are finally beginning to be understood. According to pharmacological studies, the endogenous opioid system is essential for placebo analgesia. Recent functional imaging data provides evidence that the rostral anterior cingulate cortex (rACC) represents a crucial cortical area for this type of endogenous pain control. We therefore hypothesized that placebo analgesia recruits other brain areas outside the rACC and that interactions of the rACC with these brain areas mediate opioid-dependent endogenous antinociception as part of a top-down mechanism. Nineteen healthy subjects received and rated painful laser stimuli to the dorsum of both hands, one of them treated with a fake analgesic cream (placebo). Painful stimulation was preceded by an auditory cue, indicating the side of the next laser stimulation. BOLD-responses to the painful laser-stimulation during the placebo and no-placebo condition were assessed using event-related fMRI. After having confirmed placebo related activity in the rACC, a connectivity analysis identified placebo dependent contributions of rACC activity with bilateral amygdalae and the periaqueductal gray (PAG). This finding supports the view that placebo analgesia depends on the enhanced functional connectivity of the rACC with subcortical brain structures that are crucial for conditioned learning and descending inhibition of nociception.

    Objective:To observe the effect of preemptive analgesia with parecoxib sodium on the postoperative pain and complications for patients undergoing gynecological laparoscopy. Methods:A total of 100 patients with ASA I-II grade who were admitted in our hospital from January, 2013 to February, 2014 and were undergoing gynecological laparoscopy were included in the study and randomized into the observation group and the control group. The patients in the observation group were given parecoxib sodium injection (40 mg) 30 min before operation and fentanyl citrate injection (1.0μg/kg) 30 min before the end of the surgery, while the patients in the control group were givens injections of parecoxib sodium injection (40 mg) and fentanyl citrate injection (1.0μg/kg) 30 min before the end of the surgery. The analgesia and sedation effects 4, 8, 12 h after the operation in the two groups were observed, and the postoperative additional fentanyl dosage and the adverse reactions were recorded.Results: The postoperative VAS score in each timing point and the total dosage of fentanyl in the observation group were significantly lower than those in the control group (P0.05).Conclusions: The preemptive analgesia with parecoxib sodium can reduce the dosage of postoperative analgesia medications with an accurate analgesic effect; therefore, it deserves to be widely recommended in the clinic.

    We evaluated the influence of hypnotizability, pain expectation, placebo analgesia in waking and hypnosis on tonic pain relief. We also investigated how placebo analgesia affects somatic responses (eye blink) and N100 and P200 waves of event-related potentials (ERPs) elicited by auditory startle probes. Although expectation plays an important role in placebo and hypnotic analgesia, the neural mechanisms underlying these treatments are still poorly understood. We used the cold cup test (CCT) to induce tonic pain in 53 healthy women. Placebo analgesia was initially produced by manipulation, in which the intensity of pain induced by the CCT was surreptitiously reduced after the administration of a sham analgesic cream. Participants were then tested in waking and hypnosis under three treatments: (1) resting (Baseline); (2) CCT-alone (Pain); and (3) CCT plus placebo cream for pain relief (Placebo). For each painful treatment, we assessed pain and distress ratings, eye blink responses, N100 and P200 amplitudes. We used LORETA analysis of N100 and P200 waves, as elicited by auditory startle, to identify cortical regions sensitive to pain reduction through placebo and hypnotic analgesia. Higher pain expectation was associated with higher pain reductions. In highly hypnotizable participants placebo treatment produced significant reductions of pain and distress perception in both waking and hypnosis condition. P200 wave, during placebo analgesia, was larger in the frontal left hemisphere while placebo analgesia, during hypnosis, involved the activity of the left hemisphere including the occipital region. These findings demonstrate that hypnosis and placebo analgesia are different processes of top-down regulation. Pain reduction was associated with larger EMG startle amplitudes, N100 and P200 responses, and enhanced activity within the frontal, parietal, and anterior and posterior cingulate gyres. LORETA results showed that placebo analgesia modulated pain-responsive areas

    Full Text Available BACKGROUND: Good pain relief following caesarian section is of great importance and intrathecal opioids provide good quality postoperative analgesia for longer duration. So the following study describes a comparative study between intrathecal morphine and intrathecal buprenorphine for postoperative pain relief following caesarian section (CS under subarachnoid blockade. AIMS: The study was conducted to compare intrathecal morphine and buprenorphine for post of analgesia following CS, to achieve analgesia without seda tion for better maternal child bondage and to popularize intrathecal opioids . MATERIALS AND METHODS: 60 patients posted for CS under SAB were randomly allocated into group A and group B of 30 each, the group A received morphine 0.1 mg and buprenorphine 0 . 0 3 mg was given for group B patients along with the local anaesthetic. Subjective assessment of post - operative analgesia was done by direct questioning of the patient and by a five point pain scores. Duration of analgesia was taken as the time interval betw een the time of injection of intrathecal opiate and the time at which the patient felt pain and requested for additional analgesics. Data’s were analyzed using SPSS 16th version. OBSERVATION AND RESU LTS: The mean duration of post - operative analgesia with i ntrathecal morphine was 24.19+4 . 8 hours and that with buprenorphine was only 11.7+3.28 hours. Over weight patients reported a lower mean duration of analgesia. None of the patients in the study showed any bradycardia, hypotension, desaturation or respirato ry depression. Intrathecal opiates decreased the parenteral opiate requirements. The main side effects noticed were nausea in about 43% of patients in morphine group and 33% of patients in buprenorphine group. CONCLUSIONS: Intrathecal morphine 0 . 1 mg gives good post - operative analgesia of longer duration than buprenorphine 0 . 03mg. The quality of analgesia provided by intrathecal morphine was superior to

    Full Text Available Objectives: A study to compare the efficacy between fentanyl and sufentanil combined with low concentration (0.0625% of bupivacaine for epidural labor analgesia in laboring women. Materials and Methods: Fifty full term parturients received an initial bolus dose of a 10 ml solution containing 0.125% bupivacaine. The patients were randomly divided into two: group F received 0.0625% bupivacaine with 2.5 mcg/ml fentanyl and group S received 0.0625% bupivacaine with 0.25 mcg/ml sufentanil. Verbal analogue pain scores, need of supplementary/rescue boluses dose of bupivacaine consumed, mode of delivery, maternal satisfaction, and neonatal Apgar scores were recorded. No significant difference was observed between both groups. Results: Both the groups provided equivalent labor analgesia and maternal satisfaction. The chances of cesarean delivery were also not increased in any group. No difference in the cephalad extent of sensory analgesia, motor block or neonatal Apgar score were observed. Although mean pain scores throughout the labor and delivery were similar in both groups, more patients in fentanyl group required supplementary boluses though not statistically significant. Conclusion: We conclude that both 0.0625% bupivacaine-fentanyl (2.5 μg/ml and 0.0625% bupivacaine-sufentanil (0.25 μg/ml were equally effective by continuous epidural infusion in providing labor analgesia with hemodynamic stability achieving equivalent maternal satisfaction without serious maternal or fetal side effects. We found that sufentanil was 10 times more potent than fentanyl as an analgesic for continuous epidural labor analgesia.

    Objective: Caudal epidural analgesia has become very common analgesic technique in paediatric surgery. Add-ing tramadol to bupivacaine for caudal injection prolongs duration of analgesia with minimal side effects. The aim of the study was to investigate the different effects of caudal bupivacaine versus bupivacaine with thamadol for postoperative analgesia in paediatric cancer patients. Methods: A prospective randomized controlled trial was conducted over 40 paediatric cancer pa-tients who were recruited from Children Cancer Hospital of Egypt (57357 Hospital). Patients were randomized into 2 groups: bupivacaine group (group B, 20 patients) to receive single shot caudal block of 1 mL/kg 0.1875% bupivacaine; tramadol group (group T, 20 patients) prepared as group B with the addition of 1 mg/kg caudal tramadol. Results: The mean duration of analgesia was significantly longer among group T than group B [(24 ± 13.7) hours versus (7 ± 3.7) hours respectively with P = 0.001]. Group T showed a significantly lower mean FLACC score than group B (2.2 ± 0.9 versus 3.6 ± 0.6 with P = 0.002). The difference in FLACC score was comparable on arrival, and after 2 and 4 hours. At 8 and 12 hours the group B recorded significantly higher scores (P = 0.002 and 0.0001 respectively). There were no significant differences between the groups as regards sedation score [the median in both groups was 1 (0–1) with P value = o.8]. No one developed facial flush or pruritis. Conclusion: Caudal injection of low dose tramadol 1 mg/kg with bupivacaine 0.1875% is proved to be effective, long standing technique for postoperative analgesia in major paediatric cancer surgery and almost devoid of side effect.

    Full Text Available Abstract Background Whether epidural analgesia for labor prolongs the active-first and second labor stages and increases the risk of vacuum-assisted delivery is a controversial topic. Our study was conducted to answer the question: does lumbar epidural analgesia with lidocaine affect the progress of labor in our obstetric population? Method 395 healthy, nulliparous women, at term, presented in spontaneous labor with a singleton vertex presentation. These patients were randomized to receive analgesia either, epidural with bolus doses of 1% lidocaine or intravenous, with meperidine 25 to 50 mg when their cervix was dilated to 4 centimeters. The duration of the active-first and second stages of labor and the neonatal apgar scores were recorded, in each patient. The total number of vacuum-assisted and cesarean deliveries were also measured. Results 197 women were randomized to the epidural group. 198 women were randomized to the single-dose intravenous meperidine group. There was no statistical difference in rates of vacuum-assisted delivery rate. Cesarean deliveries, as a consequence of fetal bradycardia or dystocia, did not differ significantly between the groups. Differences in the duration of the active-first and the second stages of labor were not statistically significant. The number of newborns with 1-min and 5-min Apgar scores less than 7, did not differ significantly between both analgesia groups. Conclusion Epidural analgesia with 1% lidocaine does not prolong the active-first and second stages of labor and does not increase vacuum-assisted or cesarean delivery rate.

    Ventilatory depression is a significant risk associated with the use of opioids. We assessed whether opioid-induced ventilatory depression can be selectively antagonized by an ampakine without reduction of analgesia. In 16 healthy men, after a single oral dose of 1,500 mg of the ampakine CX717, a target concentration of 100 ng/ml alfentanil decreased the respiratory frequency by only 2.9 +/- 33.4% as compared with 25.6 +/- 27.9% during placebo coadministration (P CX717 than with placebo. In contrast, CX717 did not affect alfentanil-induced analgesia in either electrical or heat-based experimental models of pain. Both ventilatory depression and analgesia were reversed with 1.6 mg of naloxone. These results support the use of ampakines as selective antidotes in humans to counter opioid-induced ventilatory depression without affecting opioid-mediated analgesia. PMID:19907420

The present study aims at comparing the hemodynamic, sedative, and analgesia potentiating effects of epidurally administered fentanyl and dexmedetomidine when combined with ropivacaine. Methods: A total of one hundred patients of both gender aged 21-56 years, American Society of Anaesthesiologist (ASA physical status I and II who underwent lower limb orthopedic surgery were enrolled into the present study. Patients were randomly divided into two groups: Ropivacaine + Dexmedetomidine (RD and Ropivacaine + Fentanyl (RF, comprising 50 patie nts each. Inj. Ropivacaine, 15 ml of 0.75%, was administered epidurally in both the groups with addition of 1 μg/kg of dexmedetomidine in RD group and 1 μg/kg of fentanyl in RF group. Besides cardio-respiratory parameters and sedation scores, various block characteristics were also observed which included time to onset of analgesia at T10, maximum sensory analgesic level, time to complete motor blockade, time to two segmental dermatomal regressions, and time to first rescue analgesic. At the end of study, data was compiled systematically and analyzed using ANOVA with post-hoc significance, Chi-square test and Fisher′s exact test.

To investigate the clinical efficacy of ultrasound and nerve stimulator guided continuous femoral nerve block analgesia after total knee arthroplasty. METHODS: 46 patients with ASA grade I-III who underwent total knee arthroplasty received postoperative analgesia from October 2012 to January 2013. In 22 patients, ultrasound and nerve stimulator guided continuous femoral nerve block were performed for analgesia (CFNB group; in 24 patients, epidural analgesia was done (PCEA group. The analgesic effects, side effects, articular recovery and complications were compared between two groups. RESULTS: At 6 h and 12 h after surgery, the knee pain score (VAS score during functional tests after active exercise and after passive excise in CFNB were significantly reduced when compared with PCEA group. The amount of parecoxib used in CFNB patients was significantly reduced when compared with PCEA group. At 48 h after surgery, the muscle strength grade in CFNB group was significantly higher, and the time to ambulatory activity was shorter than those in PCEA group. The incidence of nausea and vomiting in CFNB patients was significantly reduced when compared with PCEA group. CONCLUSION: Ultrasound and nerve stimulator guided continuous femoral nerve block provide better analgesia at 6 h and 12 h, demonstrated by RVAS and PVAS. The amount of parecoxib also reduces, the incidence of nausea and vomiting decreased, the influence on muscle strength is compromised and patients can perform ambulatory activity under this condition.

    Analgesia and sedation of patients in the neuro intensive care unit, in particular in case of intracranial hypertension, remains a challenge even today. A goal for analgesia and sedation should be set for each individual patient (RASS -5 in case of intracranial hypertension) and should be re-evaluated repeatedly based on standardized scores (RASS plus EEG monitoring where appropriate, NCS). There are no sufficient evidence-based sedation algorithms in this patient cohort. Remifentanil, sufentanil and fentanyl have been proven safe and effective for continuous application; however, bolus application should be avoided. (S-)Ketamin can be considered safe when mechanical ventilation and sedation with GABA receptor agonists are applied. Propofol and benzodiazepines are equally safe and effective with shorter wake up times for propofol. The use of barbitarutes is restricted to intractable intracranial hypertension or status epilepicus. Evidence for alpha-2-adrenoceptoragonists and inhalative sedation is poor and requires further research.

    2015-06-01

    Use of opioids to provide adequate perioperative analgesia often leads to respiratory depression, nausea, vomiting, urinary retention, pruritus, and opioid-induced hyperalgesia, with the potential to increase length of stay in the hospital. In an effort to reduce perioperative opioid administration yet provide appropriate pain relief, researchers began to study the use of esmolol beyond its well-known cardiovascular effects. Perioperative esmolol has been shown to reduce anesthetic requirements, decrease perioperative opioid use, decrease the incidence of postoperative nausea and vomiting, lead to an earlier discharge, and increase patient satisfaction. This article provides a review of the literature on the use of esmolol as an adjunct for perioperative analgesia and anesthesia. PMID:26137757

    The aim of our study is to determine the quality of postoperative analgesia by using of Perfalgan (injectable paracetamol)--alone or in combination with other analgesics for different operations in obstetric and gynecology. We have evaluated 60 women, divided into four groups each one of 15 according to the kind of surgical intervention: section cesarean, laparoscopy, laparohysterectomy or cystectomy. The effect of administered Perfalgan over postoperative pain was estimated by different objective and subjective parameters after standard general anesthesia. As a result of our study we consider that postoperative analgesia with Perfalgan is suitable enough after section cesarean and laparoscopy. As a component of multimodal analgesic combination it gives a good quality of postoperative pain relief in condition of laparohysterectomy or cystectomy. It is very important that this is without any adverse effects. PMID:16544723

    Full Text Available Acute postoperative pain has adverse effects on the patients moral as well as various physiological functions of the body. We conducted a prospective randomized study to compare the efficacy of preoperative rectal diclofenac and paracetamol for postoperative analgesia in pediatric age group. Sixty children (3 – 13 yrs. undergoing minor surgical procedures were randomly alloc ated into 2 groups, group I comprising of 30 children who received diclofenac suppository post induction and group II comprising of 30 children who received paracetamol suppository post induction. Pain was assessed by the “Hanallah pain scale” which catego rizes pain based on 5 parameters, viz, systolic blood pressure, crying, movements, agitation (confused, excited, and complaints of pain 1 . We concluded that though both, diclofenac sodium and paracetamol are good postoperative analgesics when given by rect al route in pediatric patients undergoing minor surgeries, diclofenac sodium provides better analgesia than paracetamol when given by rectal route in pediatric patients.

The technique is based on Barber's (1977) Rapid Induction Analgesia (RIA) and involves hypnotizing patients in their rooms and having their nurses provide posthypnotic cues for analgesia during wound cleaning. Five subjects who underwent hypnotherapy showed reductions on their pain rating scores (Visual Analogue Scale) relative to their own baselines and to the pain curves of a historical control group (N = 8) matched for initial pain rating scores. Although the lack of randomized assignment to experimental and control groups limited the validity of the results, the findings provide encouraging preliminary evidence that RIA offers an efficient and effective method for controlling severe pain from burns.

    The approach to sedation, analgesia, and neuromuscular blockade during targeted temperature management (TTM) remains largely unstudied, forcing clinicians to adapt previous research from other patient environments. During TTM, very little data guide drug selection, doses, and specific therapeutic goals. Sedation should be deep enough to prevent awareness during neuromuscular blockade, but titration is complex as metabolism and clearance are delayed for almost all drugs during hypothermia. Deeper sedation is associated with prolonged intensive care unit (ICU) and ventilator therapy, increased delirium and infection, and delayed wakening which can confound early critical neurological assessments, potentially resulting in erroneous prognostication and inappropriate withdrawal of life support. We review the potential therapeutic goals for sedation, analgesia, and neuromuscular blockade during TTM; the adverse events associated with that treatment; data suggesting that TTM and organ dysfunction impair drug metabolism; and controversies and potential benefits of specific monitoring. We also highlight the areas needing better research to guide our therapy. PMID:26670815

    Full Text Available SCN5A gene mutations can lead to ion channel defects which can cause cardiac conduction disturbances. In the presence of specific ECG characteristics, this mutation is called Brugada syndrome. Many drugs are associated with adverse events, making anesthesia in patients with SCN5A gene mutations or Brugada syndrome challenging. In this case report, we describe a pregnant patient with this mutation who received epidural analgesia using low dose ropivacaine and sufentanil during labour.

    Full Text Available Background and Aims: Low concentration local anaesthetic improves uteroplacental blood flow in antenatal period and during labour in preeclampsia. We compared neonatal outcome after epidural ropivacaine plus fentanyl with intramuscular tramadol analgesia during labour in high-risk parturients with intrauterine growth restriction of mixed aetiology. Methods: Forty-eight parturients with sonographic evidence of foetal weight <1.5 kg were enrolled in this non-randomized, double-blinded prospective study. The epidural (E group received 0.15% ropivacaine 10 ml with 30 μg fentanyl incremental bolus followed by 7–15 ml 0.1% ropivacaine with 2 μg/ml fentanyl in continuous infusion titrated until visual analogue scale was three. Tramadol (T group received intramuscular tramadol 1 mg/kg as bolus as well as maintenance 4–6 hourly. Neonatal outcomes were measured with cord blood base deficit, pH, ionised calcium, sugar and Apgar score after delivery. Maternal satisfaction was also assessed by four point subjective score. Results: Baseline maternal demographics and neonatal birth weight were comparable. Neonatal cord blood pH, base deficit, sugar, and ionised calcium levels were significantly improved in the epidural group in comparison to the tramadol group. Maternal satisfaction (P = 0.0001 regarding labour analgesia in epidural group was expressed as excellent by 48%, good by 52% whereas it was fair in 75% and poor in 25% in the tramadol group. Better haemodynamic and pain scores were reported in the epidural group. Conclusion: Epidural labour analgesia with low concentration local anaesthetic is associated with less neonatal cord blood acidaemia, better sugar and ionised calcium levels. The analgesic efficacy and maternal satisfaction are also better with epidural labour analgesia.

    The results analysed showed that there was a clinically significant but statistically non significant reduction in 24hr VAS score in Group I& III patients than Group II patients who had a high oestrogen level. A negative correlation between serum oestrogen and mean duration of analgesia further support this, indicating that low serum oestrogen level decreases pain sensitiv-ity and high serum oestrogen level increases pain sensitivity.

This study evaluated the effect of local anaesthesia and analgesia on vocal, physiological and behavioural responses during and after castration. A second purpose was to evaluate if herdsmen can effectively administer anaesthesia. Methods Four male piglets in each of 141 litters in five herds were randomly assigned to one of four treatments: castration without local anaesthesia or analgesia (C, controls, analgesia (M, meloxicam, local anaesthesia (L, lidocaine, or both local anaesthesia and analgesia (LM. Lidocaine (L, LM was injected at least three minutes before castration and meloxicam (M, LM was injected after castration. During castration, vocalisation was measured and resistance movements judged. Behaviour observations were carried out on the castration day and the following day. The day after castration, castration wounds were ranked, ear and skin temperature was measured, and blood samples were collected for analysis of acute phase protein Serum Amyloid A concentration (SAA. Piglets were weighed on the castration day and at three weeks of age. Sickness treatments and mortality were recorded until three weeks of age.

    Background Early studies showed that naloxone infusion decreases the incidence of morphine-related side effects from intravenous patient-controlled analgesia. This study aimed to determine whether naloxone preserved analgesia while minimizing side effects caused by intravenous tramadol administration. Methods Eighty patients undergoing general anesthesia for cervical vertebrae surgery were randomly divided into four groups. All patients received 1 mg/kg tramadol 30 minutes before the end of surgery, followed by a continuous infusion with 0.3 mgkg-1·h-1 tramadol with no naloxone (group I, n=20), 0.05 μg-kg-1·h-1 naloxone (group II, n=20), 0.1 μg·kg-1·h-1 naloxone (group III, n=20) and 0.2 μg·kg-1·h-1 naloxone (group IV, n=20). Visual analog scales (VAS) for pain during rest and cough, nausea five-point scale (NFPS) for nausea and vomiting, and ramsay sedation score (RSS) for sedation were assessed at 2, 6,12, 24 and 48 hours postoperatively. Analgesia and side effects were evaluated by blinded observers. Results Seventy-eight patients were included in this study. The intravenous tramadol administration provided the satisfied analgesia. There was no significant difference in either resting or coughing VAS scores among naloxone groups and control group. Compared with control group, sedation was less in groups II, III, and IV at 6, 12, and 24 hours (P <0.05); nausea was less in groups II, III and IV than group I at 2, 6, 12, 24 and 48 hours postoperatively (P <0.05). The incidence of vomiting in the control group was 35% vs. 10% for the highest dose naloxone group (group IV) (P<0.01). Conclusion A small-dose naloxone infusion could reduce tramadol induced side effects without reversing its analgesic effects.

    Epidural analgesia (EA) was used in 29 patients undergoing surgical removal of lumbar discal hernia. Marcain EA with controlled medicinal sleep and non-assisted breathing allowed to perform the whole operation in 27 patients. EA may be ineffective in combination of sequestrated disk hernia with scarry adhesive process. The technique of the operation demands a single use of the anesthetic drug which is potent enough to make blockade throughout the operation up to the end. PMID:10738758

    2001-02-01

    We compared in a prospective, randomized, double-blinded study the analgesic efficacy of three drugs in 120 ASA I and II patients scheduled to undergo ambulatory hand surgery with IV regional anesthesia. At discharge, oral analgesic tablets were prescribed as follows: tramadol 100 mg every 6 h, metamizol 1 g every 6 h, and paracetamol (acetaminophen) 1 g every 6 h. Rescue medication consisted of oral dextropropoxyphene 100 mg on demand. Analgesic efficacy was evaluated by self-assessment of pain intensity by visual analog score at six different time intervals during the 48-h study period. Patients also recorded global pain relief on a 5-grade scale, total number of study and rescue analgesic tablets, frequency and severity of adverse effects, sleep pattern, and overall satisfaction. None of the study drugs alone provided effective analgesia in all patients. The percentage of patients who required supplementary analgesics was 23% with tramadol, 31% with metamizol, and 42% with acetaminophen. Tramadol was the most effective analgesic, as evidenced by low pain scores, least rescue medication, and fewest number of patients with sleep disturbance. However, the incidence of side effects was also increased with tramadol. Seven patients (17.5%) withdrew from the study because of the severity of nausea and dizziness associated with the use of tramadol. Metamizol and acetaminophen provided good analgesia in about 70% and 60% of patients, respectively, with a decreased incidence of side effects. Despite receiving oral analgesic medication, up to 40% of patients undergoing hand surgery experienced inadequate analgesia in this controlled trial. Although tramadol was more effective, its use was associated with the highest frequency and intensity of adverse effects and the most patient dissatisfaction. Metamizol and acetaminophen provided good analgesia with a small incidence of side effects. For patients undergoing ambulatory hand surgery, postoperative pain can last longer than

  18. Caudal block and emergence delirium in pediatric patients: Is it analgesia or sedation?

    Directory of Open Access Journals (Sweden)

    2012-01-01

    Full Text Available Background: Emergence delirium (ED although a short-lived and self-limiting phenomenon, makes a child prone to injury in the immediate postoperative period and hence is a cause of concern not only to the pediatric anesthesiologist, surgeons, and post anesthesia care unit staff but also amongst parents. Additional medication to quieten the child offsets the potential benefits of rapid emergence and delays recovery in day care settings. There is conflicting evidence of influence of analgesia and sedation following anesthesia on emergence agitation. We hypothesized that an anesthetic technique which improves analgesia and prolongs emergence time will reduce the incidence of ED. We selected ketamine as adjuvant to caudal block for this purpose. Methods: This randomized, double blind prospective study was performed in 150 premedicated children ASA I, II, aged 2 to 8 years who were randomly assigned to either group B (caudal with bupivacaine, BK (bupivacaine and ketamine, or NC (no caudal, soon after LMA placement. Recovery characteristics and complications were recorded. Results: Emergence time, duration of pain relief, and Pediatric Anesthesia Emergence Delirium (PAED scores were significantly higher in the NC group (P<0.05. Duration of analgesia and emergence time were significantly more in group BK than groups B and NC. However, the discharge readiness was comparable between all groups. No patient in BK group required to be given any medication to treat ED. Conclusion: Emergence time as well as duration of analgesia have significant influence on incidence of emergence delirium. Ketamine, as caudal adjuvant is a promising agent to protect against ED in children, following sevoflurane anesthesia.

    Background A wealth of evidence has indicated that labor epidural analgesia is associated with an increased risk of hyperthermia and overt clinical fever.Recently,evidence is emerging that the epidural analgesia-induced fever is associated with the types of the epidural analgesia and the variations in the epidural analgesia will affect the incidence of fever.The aim of the present study was to investigate the effects of epidural analgesia with 0.075% or 0.1%ropivacaine on the maternal temperature during labor.Methods Two hundred healthy term nulliparas were randomly assigned to receive epidural analgesia with either 0.1% ropivacaine or 0.075% ropivacaine.Epidural analgesia was initiated with 10 ml increment of the randomized solution and 0.5 μg/ml sufentanyl after a negative test dose of 5 ml of 1.5% lidocaine,and maintained with 7 ml bolus doses of the abovementioned mixed analgesics every 30 minutes by the patient-controlled epidural analgesia.The measurements included the maternal oral temperature,visual analog scale pain scores,labor events and neonatal outcomes.Results Epidural analgesia with 0.075% ropivacaine could significantly lower the mean maternal temperature at 4 hours after the initiation of analgesia and the oxytocin administration during labor compared with the one with 0.1%ropivacaine.Moreover,0.075% ropivacaine treatment could provide satisfactory pain relief during labor and had no significant adverse effects on the labor events and neonatal outcomes.Conclusion Epidural analgesia with 0.075% ropivacaine may be a good choice for the epidural analgesia during labor.

    Full Text Available Background: For lower abdomen and lower limb surgery, spinal anaesthesia is most common modality used in routine. This study was conducted on 50 ASA 1 and 2 planned for lower limb and lower abdomen surgery. Methods: 50 patients of ASA 1 and 2 scheduled for lower limb and lower abdominal surgery were selected. Each patient received 4 milliliter volume of 0.75% isobaric ropivacaine + 5 microgram dexmedetomidine. At the intervals of 1 minute, 2 minute, 5 minute, 10 minute, 20 minute, 30 minute and 1 hour, 2 hour and 3 hour reading of pulse rate and blood pressure were recorded. Postoperatively, pain scores were recorded by using Visual Analogue Scale. Results: There were no significant changes in systolic and diastolic blood pressure after induction. The combination of ropivacaine and dexmedetomidine provided better postoperative analgesia and reduced requirement of diclofenac injection in first 24 hour. Conclusions: The patients showed excellent hemodynamic stability and postoperative analgesia to ropivacaine + dexmedetomidine. Thus it is a safe modality for lower limb and lower abdomen surgery as far as haemodynamic effects and postoperative analgesia is concerned. [Int J Basic Clin Pharmacol 2013; 2(1.000: 26-29

    2012-02-01

    BACKGROUND: Ward-based patient-controlled epidural analgesia (PCEA) for postoperative pain control was introduced at our institution in 2006. We audited the efficacy and safety of ward-based PCEA from January 2006 to December 2008. METHOD: Data were collected from 928 patients who received PCEA in general surgical wards for postoperative analgesia using bupivacaine 0.125% with fentanyl 2 mug\\/mL. RESULTS: On the first postoperative day, the median visual analogue pain score was 2 at rest and 4 on activity. Hypotension occurred in 21 (2.2%) patients, excessive motor blockade in 16 (1.7%), high block in 5 (0.5%), nausea in 5 (0.5%) and pruritus in only 1 patient. Excessive sedation occurred in two (0.2%) patients but no intervention was required. There were no serious complications such as epidural abscess, infection or haematoma. CONCLUSION: Effective and safe postoperative analgesia can be provided with PCEA in a general surgical ward without recourse to high-dependency supervision.

  6. Placebo analgesia and its opioidergic regulation suggest that empathy for pain is grounded in self pain.

    Empathy for pain activates brain areas partially overlapping with those underpinning the first-hand experience of pain. It remains unclear, however, whether such shared activations imply that pain empathy engages similar neural functions as first-hand pain experiences. To overcome the limitations of previous neuroimaging research, we pursued a conceptually novel approach: we used the phenomenon of placebo analgesia to experimentally reduce the first-hand experience of pain, and assessed whether this results in a concomitant reduction of empathy for pain. We first carried out a functional MRI experiment (n = 102) that yielded results in the expected direction: participants experiencing placebo analgesia also reported decreased empathy for pain, and this was associated with reduced engagement of anterior insular and midcingulate cortex: that is, areas previously associated with shared activations in pain and empathy for pain. In a second step, we used a psychopharmacological manipulation (n = 50) to determine whether these effects can be blocked via an opioid antagonist. The administration of the opioid antagonist naltrexone blocked placebo analgesia and also resulted in a corresponding "normalization" of empathy for pain. Taken together, these findings suggest that pain empathy may be associated with neural responses and neurotransmitter activity engaged during first-hand pain, and thus might indeed be grounded in our own pain experiences.

    Placebo treatments reliably reduce pain in the clinic and in the lab. Because pain is a subjective experience, it has been difficult to determine whether placebo analgesia is clinically relevant. Neuroimaging studies of placebo analgesia provide objective evidence of placebo-induced changes in brain processing and allow researchers to isolate the mechanisms underlying placebo-based pain reduction. We conducted formal meta-analyses of 25 neuroimaging studies of placebo analgesia and expectancy-based pain modulation. Results revealed that placebo effects and expectations for reduced pain elicit reliable reductions in activation during noxious stimulation in regions often associated with pain processing, including the dorsal anterior cingulate, thalamus, and insula. In addition, we observed consistent reductions during painful stimulation in the amygdala and striatum, regions implicated widely in studies of affect and valuation. This suggests that placebo effects are strongest on brain regions traditionally associated with not only pain, but also emotion and value more generally. Other brain regions showed reliable increases in activation with expectations for reduced pain. These included the prefrontal cortex (including dorsolateral, ventromedial, and orbitofrontal cortices), the midbrain surrounding the periaqueductal gray, and the rostral anterior cingulate. We discuss implications of these findings as well as how future studies can expand our understanding of the precise functional contributions of the brain systems identified here.

    Several studies have shown that psychological factors such as learning, expectation, and emotions can affect pharmacological treatment and shape both favorable and adverse effects of drugs. This study investigated whether nocebo information provided during administration of an analgesic cream could reverse topical analgesia to hyperalgesia. Furthermore, we tested whether nocebo effects were mediated by negative emotional activation. A total of 142 healthy volunteers (73 women) were randomized into 6 groups. A topical analgesic cream (Emla) was administered together with suggestions of analgesia in 1 group, whereas another group received Emla with suggestions of hyperalgesia. Two other groups received a placebo cream together with the same information as the groups receiving Emla. A fifth group received Emla with no specific information about the effect, and the sixth group received no treatment but the same pain induction as the other groups. Heat pain stimulation (48°C) was administered during a pretest and 2 posttests. Pain was continuously recorded during stimulation, and measures of subjective stress and blood pressure were obtained before the pretest, after the application of cream, and after the posttests. The results revealed that pain was significantly lower in the group receiving Emla with positive information and highest in the groups receiving suggestions of hyperalgesia, regardless of whether Emla or the placebo was administered. Mediation analyses showed that stress and blood pressure mediated hyperalgesia after nocebo suggestions. These results suggest that nocebo information can reverse topical analgesia and that emotional factors can explain a significant proportion of variance in nocebo hyperalgesia.

  9. Neuroimmune Interaction in the Regulation of Peripheral Opioid-Mediated Analgesia in Inflammation.

    Science.gov (United States)

    Hua, Susan

    2016-01-01

    Peripheral immune cell-mediated analgesia in inflammation is an important endogenous mechanism of pain control. Opioid receptors localized on peripheral sensory nerve terminals are activated by endogenous opioid peptides released from immune cells to produce significant analgesia. Following transendothelial migration of opioid-containing leukocytes into peripheral sites of inflammation, opioid peptides are released into a harsh milieu associated with an increase in temperature, low pH, and high proteolytic activity. Together, this microenvironment has been suggested to increase the activity of opioid peptide metabolism. Therefore, the proximity of immune cells and nerve fibers may be essential to produce adequate analgesic effects. Close associations between opioid-containing immune cells and peripheral nerve terminals have been observed. However, it is not yet determined whether these immune cells actually form synaptic-like contacts with peripheral sensory terminals and/or whether they secrete opioids in a paracrine manner. This review will provide novel insight into the peripheral mechanisms of immune-derived analgesia in inflammation, in particular, the importance of direct interactions between immune cells and the peripheral nervous system.

Patients and Methods: A total of 90 patients, aged 20-50 years, undergoing hemorrhoidectomy were randomly scheduled to receive bupivacaine 0.25% in 20 ml (Group B; n = 30), tramadol 1 mg/kg in 20 ml (Group T1; n = 30), tramadol 2 mg/kg in 20 ml (Group T2; n = 30) through caudal route after induction of general anesthesia. Postoperative pain was assessed every hour until the visual analog scale was 6, which is 1st time for rescue analgesia. Postoperative sedation, hemodynamic changes, serum cortisol, and epinephrine levels and incidence of side effects were also evaluated. Results: Duration of analgesia was longer in Group T2 (20 [1.14] h] compared with the Group B (7 [1.2] h) or Group T1 (12 [0.75] h); all P < 0.001. There were no significant hemodynamic changes. There were not incidences of side effects. Conclusion: Caudal tramadol 2 mg/kg provided a longer duration of postoperative analgesia with rapid onset and no incidence of complications or adverse effects in adult hemorrhoidectomy.

    Full Text Available This study was performed to investigate the analgesic effect of lidocaine and a combination of lidocaine and ketamine following epidural administration in dromedary camels. Ten 12–18-month-old camels were randomly divided into two equal groups. In group L, the animals received 2% lidocaine (0.22 mg/kg and in group LK the animals received a mixture of 10% ketamine (1 mg/kg and 2% lidocaine (0.22 mg/kg administered into the first intercoccygeal (Co1–Co2 epidural space while standing. Onset time and duration of caudal analgesia, sedation level and ataxia were recorded after drug administration. Data were analysed by U Mann-Whitney tests and significance was taken as p < 0.05. The results showed that epidural lidocaine and co-administration of lidocaine and ketamine produced complete analgesia in the tail, anus and perineum. Epidural administration of the lidocaine-ketamine mixture resulted in mild to moderate sedation, whilst the animals that received epidural lidocaine alone were alert and nervous during the study. Ataxia was observed in all test subjects and was slightly more severe in camels that received the lidocaine-ketamine mixture. It was concluded that epidural administration of lidocaine plus ketamine resulted in longer caudal analgesia in standing conscious dromedary camels compared with the effect of administering lidocaine alone.

  12. Neuroimmune Interaction in the Regulation of Peripheral Opioid-Mediated Analgesia in Inflammation.

    2016-01-01

    Peripheral immune cell-mediated analgesia in inflammation is an important endogenous mechanism of pain control. Opioid receptors localized on peripheral sensory nerve terminals are activated by endogenous opioid peptides released from immune cells to produce significant analgesia. Following transendothelial migration of opioid-containing leukocytes into peripheral sites of inflammation, opioid peptides are released into a harsh milieu associated with an increase in temperature, low pH, and high proteolytic activity. Together, this microenvironment has been suggested to increase the activity of opioid peptide metabolism. Therefore, the proximity of immune cells and nerve fibers may be essential to produce adequate analgesic effects. Close associations between opioid-containing immune cells and peripheral nerve terminals have been observed. However, it is not yet determined whether these immune cells actually form synaptic-like contacts with peripheral sensory terminals and/or whether they secrete opioids in a paracrine manner. This review will provide novel insight into the peripheral mechanisms of immune-derived analgesia in inflammation, in particular, the importance of direct interactions between immune cells and the peripheral nervous system.

    Full Text Available CONTEXT: Various adjuvants such as opioids or α2 agonists are being used to improve the quality and duration of caudal analgesia with local anesthetics. Dexmedetomidine a α2 agonist is used frequently in adult patients to enhance the local anesthetic effect. However there is little literature regarding its effectiveness in pediatric caudal analgesia. The objective of this study was to assess the efficacy of dexmedetomidine when used as an adjuvant to bupivacaine in increasing the duration of caudal analgesia. AIM: The aim of this study was to investigate the effect of adding Dexmedetomidine to caudal Bupivacaine and observe the effect on the duration of analgesia in the post-operative period. SETTINGS AND DESIGN: One year hospital based Double Blind Randomized Controlled Trial. METHODS AND MATERIAL: Sixty children, aged 1-6 years, undergoing lower abdominal surgeries were included in this prospective randomized double-blind study. The patients were randomly divided into two groups: Group I received Bupivacaine (0.25% 1ml/kg plus 1 ml of normal saline in the caudal epidural space. Group II was administered Bupivacaine (0.25% 1ml/ with Dexmedetomidine 2 mcg/ ml diluted to 1 ml of normal saline in the caudal epidural space. All anesthetic and surgical techniques were standardized. Heart rate, blood pressure, oxygen saturation, respiratory rate were monitored continuously. Surgery was started 10-15 minutes after the injection and confirming adequacy of caudal block. Duration of analgesia was assessed using FLACC scale (Face, Legs, Activity, Cry, Consolability scale. The time from administration of caudal anesthesia to the first time the FLACC score equal or greater than 4 was considered as the duration of caudal analgesia. Paracetamol suppository was used as rescue analgesia with a loading dose of 40mg/kg. STATISTICAL ANALYSIS: Mann-Whitney test and Student ‘t’test was used to compare the data obtained in the two groups. RESULTS: The

    Full Text Available Introduction: Recent studies have shown that cold water swimming stress (CWSS produces analgesia. Although exact mechanism of the analgesia is until unclear, it may attributed to CCK receptors. On the other hand, the effectiveness of analgesic drugs for treatment of neuropathic pain is limited. In the present study, the effects of CCK receptor agonist caerulein and antagonist proglumide , both alone and together on the CWSS- induced analgesia was investigated and compared in normal mice and those whose sciatic nerve was ligated. Material & Methods: In this research, fifty groups of nine male albino mice were used. As a model of neuropathy, the unilateral nerve ligation was made by a surgical procedure on the right hind limb. Pain sensitivity was measured by the hot plate test. Results: Different CWSS regimes (0.5-3 min induced time-dependent analgesia. Nerve ligation did not alter the CWSS induced analgesia. Caerulein (0.025, 0.05 and 0.1 mg/kg induced analgesia in both nerve ligated and intact animals. Different doses of proglumide (20, 40 and 60 mg/kg alone produced analgesic effect. The response of caerulein was not inhibited by proglumide. In the stressed mice, both drugs and the combination of them showed analgesia but there appeared to be no potentiation in CWSS- induced analgesia. Our results indicate no significant relationship between CCK receptors and the CWSS- induced analgesia. Conclusion: Nevertheless, CWSS as an alternative to drug treatment in neuropathic pain requires more studies.

    Full Text Available Introducción: La analgesia epidural se ha popularizado en España, tanto en su conocimiento como en su uso, a lo largo de los últimos 20 años. La elección de esta técnica analgésica por parte de la futura madre durante el trabajo de parto y el parto en Andalucía es un derecho de la mujer que, explícitamente, sólo estará limitado por sus condiciones físicas y de salud y por los recursos disponibles en el hospital en el momento del parto. Esta elección pone en relación 2 elementos: por un lado, el componente cognitivo que establece la conveniencia o no de utilizar esta técnica según los valores, percepciones, cultura, etc. de la mujer y, por otro, el componente conductual, es decir, el uso o no de la técnica en cuestión, que dependerá además de la elección de la mujer de las condiciones anteriormente mencionadas. Objetivo: Analizar qué características definen a las mujeres que, aun pudiendo, deciden no utilizar analgesia epidural durante el parto en Andalucía. Material y métodos: Para ello se ha utilizado la información proporcionada por las mujeres ingresadas por parto en los hospitales del Sistema Sanitario Público de Andalucía, contenida en las encuestas anuales de satisfacción de usuarios del sistema de atención hospitalario en esta comunidad autónoma entre los años 2000 y 2007. Con esta información se ha realizado un análisis de segmentación jerárquica que tenía por objetivo analizar el perfil de las mujeres que rechazan esta técnica analgésica. Resultados: Las principales características que definen a las mujeres que rechazan la analgesia epidural durante el parto vienen dadas por su nivel educativo, nivel de ingresos y situación laboral. Conclusiones: Las características sociales, económicas y culturales que definen el rechazo, es decir, el "tipo" de mujer que rehúsa la epidural, coinciden con el esquema de "mujer tradicional" estudiado por otros autores (que se caracteriza por tener escasos

    Full Text Available Con base en la premisa de que la lectura de textos literarios tiene una función formadora y que esta se acentúa en la adolescencia, me propongo demostrar que el cuento “Rapunzel” puede utilizarse como estrategia para explorar algunas situaciones que los sujetos adolescentes perciben como particulares en relación con su vida, pero que se inscriben dentro de grandes problemáticas estudiadas por varias disciplinas. Para ello, he identificado, desde dos marcos de referencia (sociológico y psicoanalítico, diversas problemáticas y discursos que se desprenden de la lectura del cuento realizada por dos mujeres adolescentes, quienes respondieron una guía de lectura y participaron en una entrevista a profundidad. Concluyo que la lectura y comentario del cuento hacen posible que una serie de experiencias que los sujetos adolescentes viven como únicas (como el embarazo de una amiga, las críticas de las personas adultas y las exigencias de padres y madres, ingresen en el circuito de los conocimientos generales al relacionarlas con los discursos y problemáticas en que se inscriben (por ejemplo, el discurso de la “crisis” de la adolescencia, el enfoque de derechos humanos, el mundo fantasmático materno. Por ello, recomiendo la lectura y comentario de textos literarios como estrategia didáctica para contribuir a la elaboración de la subjetividad de personas adolescentes.

    Casi la generalidad de los estudios realizados sobre cementos con adición de cenizas volantes se refieren a sus características y comportamiento en pastas, morteros y hormigones, siempre en relación con aquéllos del cemento portland. Esta vez, se desarrolló un trabajo experimental orientado a relacionar entre sí los cementos con adiciones de cenizas volantes y de puzolana natural. Para ello se fabricaron a escala de laboratorio cementos de ambos tipos, empleando como materias primas comunes clinker y yeso y, como variables, diferentes porcentajes de las dos adiciones, que cumplieron previamente los requisitos normalizados en cuanto a sus actividades puzolánicas. La calidad de los cementos fabricados resultó adecuada y concordante con la del cemento portland-puzolánico obtenido a escala industrial con los mismos clinker, yeso y puzolana natural de este estudio. Posteriormente, se determinaron las características de los cementos experimentales y se confeccionaron morteros normales para la realización de ensayos físicos y mecánicos. Los resultados de ensayos indicaron que los cementos con adición de cenizas volantes (CCV requieren menos agua para consistencia normal, presentan tiempos de fraguado mayores y expansiones en autoclave menores que los cementos con adición de puzolana (CP. Los calores de hidratación a 7 y 28 días de edad fueron aproximadamente similares para ambos tipos de cemento. En morteros normales, los cementos CCV mostraron menor retracción de secado, mayor retentividad y mayor fluidez (para igual cantidad de agua que los cementos CP. En los ensayos de exudación se observó que ésta depende más de la finura que el tipo de adición. Finalmente, los ensayos mecánicos señalaron que las resistencias a compresión y flexotracción de los morteros con cementos CCV son menores a edades inferiores que 14 días (del orden de 5 a 10% a un día de edad, pero que a partir de entonces pasan a ser mayores que las de

    Background Ropivacaine and levobupivacaine have been introduced into obstetric analgesic practice with the proposed advantages of causing less motor block and toxicity compared with bupivacaine. However, it is still controversial whether both anesthetics are associated with any clinical benefit relative to bupivacaine for labor analgesia. This study aimed to compare the analgesic efficacy, motor block and side effects of bupivacaine, ropivacaine and levobupivacaine at lower concentrations for patient-controlled epidural labor analgesia. Methods Four hundred and fifty nulliparous parturients were enrolled in this randomized clinical trial. A concentration of 0.05%, 0.075%, 0.1%, 0.125% or 0.15% of either bupivacaine (Group B), ropivacaine (Group R) or levobupivacaine (Group L) with sufentanil 0.5 μg/ml was epidurally administered by patient-controlled analgesia mode. Effective analgesia was defined as a visual analogue scale score was ≤30 mm. The relative median potency for each local anesthetic was calculated using a probit regression model. Parturients demographics, sensory and motor blockade, obstetric data, maternal side effects, hourly volumes of local anesthetic used, and others were also noted. Results There were no significant differences among groups in the numbers of effective analgesia, pain scores, hourly local anesthetic amount used, sensory and motor blockade, labor duration and mode of delivery, side effects and maternal satisfaction (P >0.05). The relative median potency was bupivacaine/ropivacaine: 0.828 (0.602-1.091), bupivacaine/levobupivacaine: 0.845 (0.617-1.12), ropivacaine/levobupivacaine: 1.021 (0.774-1.354), respectively. However, a significantly less number of effective analgesia and higher hourly local anesthetic use were observed in the concentration of 0.05% than those of ≥0.1% within each group (P<0.05). Conclusions Using patient-controlled epidural analgesia, lower concentrations of bupivacaine, ropivacaine and levobupivacaine

    In a previous study, we showed that electroacupuncture (EA) applied to the SI-6 point on the contralateral forelimb produces long-lasting and powerful analgesia in pain caused by ankle sprain in a rat model. To investigate the underlying mechanism of EA analgesia, the present study tested the effects of various antagonists on known endogenous analgesic systems in this model. Ankle sprain was induced in anesthetized rats by overextending their right ankle with repeated forceful plantar flexion and inversion of the foot. When rats developed pain behaviors (a reduction in weight-bearing of the affected hind limb), EA was applied to the SI-6 point on the contralateral forelimb for 30 min under halothane anesthesia. EA significantly improved the weight-bearing capacity of the affected hind limb for 2h, suggesting an analgesic effect. The alpha-adrenoceptor antagonist phentolamine (2mg/kg, i.p. or 30 microg, i.t.) completely blocked the EA-induced analgesia, whereas naloxone (1mg/kg, i.p.) failed to block the effect. These results suggest that EA-induced analgesia is mediated by alpha-adrenoceptor mechanisms. Further experiments showed that intrathecal administration of yohimbine, an alpha(2)-adrenergic antagonist, reduced the EA-induced analgesia in a dose-dependent manner, whereas terazosin, an alpha(1)-adrenergic antagonist, did not produce any effect. These data suggest that the analgesic effect of EA in ankle sprain pain is, at least in part, mediated by spinal alpha(2)-adrenoceptor mechanisms. PMID:17537577

    Full Text Available Um sistema reparável opera sob uma política de manutenção que especifica reparos preventivos em tempos pré-determinados e reparos mínimos quando ocorre uma falha. O processo de Poisson não-homogêneo é um modelo adequado para as falhas aleatórias que são tratadas por reparo mínimo. Assumindo um único tipo de falha e uma forma paramétrica para a função de intensidade deste processo, pode-se encontrar uma política ótima de manutenção preventiva que minimiza o custo médio por unidade de tempo. Este artigo foi motivado por uma situação envolvendo chaves seccionadoras de uma empresa de energia elétrica. Neste sistema existem dois tipos diferentes de eventos aleatórios, caracterizados por distintas causas de falhas. Uma política ótima de manutenção preventiva é obtida estendendo-se os resultados da situação envolvendo um único evento aleatório.A repairable system operates under a maintenance strategy that calls for complete preventive repair actions at pre-scheduled times and minimal repair actions whenever a failure occurs. Under minimal repair, failures are modeled according to a non-homogeneous Poisson process. When the intensity function is assumed to grow proportional to a power of time, this process is called the Power Law Process. The motivation for this paper was a maintenance data set related to power switch disconnectors. Two different types of failures could be observed for these systems according to their causes. The major differences between these types of failures are their costs. Assuming that the system will be in operation for an infinite time, we found the expected cost per unit of time for each preventive maintenance policy and hence obtained the optimal strategy as a function of the intensity function of the process. Large sample procedures to estimate the optimal maintenance check points for the Power Law Process are also discussed. The results are applied in the power switch disconnector data set.

    The purpose of this study was to investigate whether regression of sensory analgesia during constant epidural bupivacaine infusion was different in postoperative patients with acute pain than in patients with chronic nonsurgical pain. Sensory levels of analgesia (to pinprick) and pain (on a five......-point scale) were assessed hourly for 16 hours during continuous epidural infusion of 0.5% plain bupivacaine (8 ml/hr) in 12 patients with chronic nonsurgical pain and in 30 patients after major abdominal surgery performed under combined bupivacaine and halothane--N2O general anesthesia. No opiates were given.......01). Mean duration of sensory blockade was significantly longer (P less than 0.005) in the patients with chronic pain than in surgical patients (13.1 +/- 1.2 and 8.5 +/- 0.7 hours, respectively). Thus, surgical injury hastens regression of sensory analgesia during continuous epidural bupivacaine infusion...

    Full Text Available Objective To observe the effect of forgetful analgesia induction and tracheal intubation on the hemodynamic changes in induction period in patients with obstructive jaundice, and explore a safe method for anesthesia induction and tracheal intubation. Methods Sixty patients with obstructive jaundice undergoing elective abdominal operation in General Hospital of PLA from February, 2013 to August, 2013 were involved in the present study. Participants included 36 male and 24 female patients, aging 19-65 years (mean 42±5 years, weighing 47-73 kg (mean 54±6 kg, with ASA Ⅰ-Ⅱ. These 60 patients were randomly divided into forgetful analgesia induction-tracheal intubation group (group A, n=30 and rapid induction-tracheal intubation group (group B, n=30. The heart rate (HR, mean arterial pressure (MAP, pulse oxygen saturation (SpO2 at the time point of before induction (T0, before intubation (T1, at the moment of intubation (T2 and 3 min after intubation (T3 were determined in both groups. Administration times of ephedrine hydrochloride and atropine was recorded in both groups. Results There was no significant difference in HR, MAP, SpO2 before and after induction in group A. In the patients of group B, the HR increased and MAP decreased after induction compared with those before induction (P<0.05, and the change of SpO2 was not significant. Ephedrine hydrochloride and atropine were administrated in both groups, and the cases and times of ephedrine hydrochloride administration were more in group B than in group A (P<0.05. Conclusion The forgetful analgesia induction-tracheal intubation could effectively control the stress response and reduce the fluctuation in hemodynamics during induction of anesthesia in patients with obstructive jaundice.

  18. Synergistic analgesia of duloxetine and celecoxib in the mouse formalin test: a combination analysis.

    Yong-Hai Sun

    Full Text Available Duloxetine, a serotonin and noradrenaline reuptake inhibitor, and celecoxib, a non-steroidal anti-inflammatory drug, are commonly used analgesics for persistent pain, however with moderate gastrointestinal side effects or analgesia tolerance. One promising analgesic strategy is to give a combined prescription, allowing the maximal or equal efficacy with fewer side effects. In the current study, the efficacy and side effects of combined administration of duloxetine and celecoxib were tested in the mouse formalin pain model. The subcutaneous (s.c. injection of formalin into the left hindpaw induced significant somatic and emotional pain evaluated by the biphasic spontaneous flinching of the injected hindpaw and interphase ultrasonic vocalizations (USVs during the 1 h after formalin injection, respectively. Pretreatment with intraperitoneal (i.p. injection of duloxetine or celecoxib at 1 h before formalin injection induced the dose-dependent inhibition on the second but not first phase pain responses. Combined administration of duloxetine and celecoxib showed significant analgesia for the second phase pain responses. Combination analgesia on the first phase was observed only with higher dose combination. A statistical difference between the theoretical and experimental ED50 for the second phase pain responses was observed, which indicated synergistic interaction of the two drugs. Concerning the emotional pain responses revealed with USVs, we assumed that the antinociceptive effects were almost completely derived from duloxetine, since celecoxib was ineffective when administered alone or reduced the dosage of duloxetine when given in combination. Based on the above findings, acute concomitant administration of duloxetine and celecoxib showed synergism on the somatic pain behavior but not emotional pain behaviors.

    Pain requires the integration of sensory, cognitive, and affective information. The use of placebo is a common methodological ploy in many fields, including pain. Neuroimaging studies of pain and placebo analgesia (PA) have yet to identify a mechanism of action. Because PA must result from higher order processes, it is likely influenced by cognitive and affective dimensions of the pain experience. A network of brain regions involved in these processes includes the anterior and posterior insula (A-Ins, P-Ins), dorsal anterior cingulate cortex (DACC), dorsolateral prefrontal cortex (DLPFC), and the supplementary motor area (SMA). We used connectivity analyses to investigate the underlying mechanisms associated with Placebo analgesia in a group of chronic pain patients. Structural equation models (SEM) of fMRI data evaluated the inter-regional connectivity of these regions across three conditions: (1) initial Baseline (B1), (2) placebo (PA), and (3) Placebo Match (PM). SEM results of B1 data in the left hemisphere confirmed hypothesized regional relationships. However, inter-regional relationships were dynamic and the network models varied across hemispheres and conditions. Deviations from the B1 model in the PA and PM conditions correspond to our manipulation of expectation for pain. The dynamic changes in inter-regional influence across conditions are interpreted in the context of a self-reinforcing feedback loop involved in the induction and maintenance of PA. Although it is likely that placebo analgesia results partly from afferent inhibition of a nociceptive signal, the mechanisms likely involve the interaction of a cognitive-affective network with input from both hemispheres.

    Full Text Available Rostral spread of intrathecal drugs and sensitization of supraspinal sites may provoke several adverse effects. This case describes a patient with right hemifacial paresthesia, trismus and dysphasia on the trigeminal nerve distribution after intrathecal sufentanil administration. Primigravida, 34 years, 39 weeks of pregnancy, with hypothyroidism and pregnancy induced hypertension. Allergic to latex. In the use of puran T4, 50 μg /day. When the patient presented cervical dilatation of 4 cm, she requested analgesia. She was placed in the sitting position and a spinal puncture was performed with a 27G needle pencil point in L4/L5 (1.5 mg of bupivacaine plus 7.5 μg of sufentanil. Next, was performed an epidural puncture in the same space. It was injected bupivacaine 0.065%, 10 ml, to facilitate the passage of the catheter. After 5 min lying down in the lateral upright position, she complained of perioral and right hemifacial paresthesia, mainly maxillary and periorbital, as well as trismus and difficulty to speak. The symptoms lasted for 30 min and resolved spontaneously. After 1 h, patient requested supplementary analgesia (12 ml of bupivacaine 0.125% and a healthy baby girl was born. Temporary mental alterations have been described with the use of fentanyl and sufentanil in combined epidural-spinal analgesia, such as aphasia, difficulty of swallowing, mental confusion and even unconsciousness. In this patient, facial areas with paresthesia indicated by patient appear in clear association with the ophthalmic and maxillary branches of the trigeminal nerve and the occurrence of trismus and dysphagia are in association with the mandibular motor branch. The exact mechanism of rostral spread is not known, but it is speculated that after spinal drug administration, a subsequent epidural dose may reduce the intratecal space and propel the drug into the supraspinal sites.

    Full Text Available Background: Establishing an epidural in an agitated laboring woman can be challenging. The ideal pain control technique in such a situation should be effective, fast acting, and short lived. We assessed the efficacy of inhalational methoxyflurane (Penthrox™ analgesia as bridging analgesia for epidural placement. Materials and Methods: Sixty-four laboring women who requested epidural analgesia with pain score of ≥7 enrolled in an observational study, 56 of which completed the study. The parturients were instructed to use the device prior to the onset of uterine contraction pain and to stop at the peak of uterine contraction, repeatedly until epidural has been successfully placed. After each (methoxyflurane inhalation-uterine contraction cycle, pain, Richmond Agitation Sedation Scale (RASS, nausea and vomiting were evaluated. Maternal and fetal hemodynamics and parturient satisfaction were recorded. Results: The mean baseline pain score was 8.2 ± 1.5 which was reduced to 6.2 ± 2.0 after the first inhalation with a mean difference of 2.0 ± 1.1 (95% confidence interval 1.7-2.3, P < 0.0001, and continued to decrease significantly over the study period (P < 0.0001. The RASS scores continuously improved after each cycle (P < 0.0001. Only 1 parturient from the cohort became lightly sedated (RASS = −1. Two parturients vomited, and no significant changes in maternal hemodynamics or fetal heart rate changes were identified during treatment. 67% of the parturients reported very good or excellent satisfaction with treatment. Conclusion: Penthrox™ provides rapid, robust, and satisfactory therapy to control pain and restlessness during epidural placement in laboring parturient.

    Full Text Available Introduction: Opioid receptors have been demonstrated in the peripheral nerve endings of afferent neurons. Blockade of these receptors with peripherally administered opioid is believed to result in analgesia. Aim: To evaluate whether buprenorphine added to bupivacaine for wound infiltration can enhance post-operative analgesia via peripheral mechanisms. Materials and Methods: Forty ASA I and II adult patients scheduled for open donor nephrectomy were enrolled in this randomized double blind prospective study. In group A ( n=20 patients, the wound was infiltrated with bupivacaine 0.5% (2 mg/kg and in group B ( n=20 with bupivacaine 0.5% (2 mg/kg and buprenorphine (2 μg/kg. All patients were given diclofenac 75 mg IM at 8 h interval. Post-operative quality of analgesia was assessed by VAS (0-10 for 24 h and when VAS > 4 rescue analgesic was administered. Total dose of rescue analgesic and side effects were noted. Results: The time of administration of first rescue analgesic was significantly higher in group B (10.52±5.54 h as compared to group A (3.275±1.8 h. Mean VAS was significantly lower in group B as compared to group A. The total dosage of rescue analgesic was more in group A as compared to group B patients. Conclusion: Addition of buprenorphine to the local anesthetic significantly prolonged the time to first rescue analgesic requirement and the total consumption of rescue analgesic in 24 h, thus providing evidence in support of the existence of peripheral opioid receptors.

    Postsurgical oral self-administration of analgesics in rodents is an interesting technique of providing analgesia, avoiding the negative effects of manipulation. Several strategies, using gelatin or nutella, have already been described. However, rodents require some habituation period to reach a good intake because of their neophobic behavior. The current study aimed to explore whether buprenorphine when mixed with an extruded diet offers a potential treatment option in the pain management of mice using a triple approach: by measuring the spontaneous intake in healthy animals; by using the hot-plate test; and finally by assessing the drug's ability to provide postoperative analgesia in a surgical intervention of moderate severity (intra-utero electroporation). Mice consumed during 20 hours, similar amounts of extruded diet alone, mixed with glucosaline, and mixed with buprenorphine (0.03 mg per pellet) or meloxicam (0.25 mg per pellet) both of which were diluted in glucosaline, showing that no neophobia was associated with these administrations. Relative increase from baseline latency (% maximal possible effect) in the hot-plate test at 20 h of administration was significantly higher for oral buprenorphine in diet 0.03 mg/pellet, and diet 0.15 mg/pellet, compared with placebo and no differences were found between those oral administrations and subcutaneous buprenorphine 0.1 mg/kg measured 3 h later. The treatment was also effective in attenuating the reductions in food consumption and body weight that occur after surgery. These data suggest that providing buprenorphine with the diet is a feasible and effective way of self-administration of analgesia in mice and does not cause neophobia and may easily contribute to the refinement of surgical procedures.

    Full Text Available Background and Aims: Caudal block (CB with adjuvants is routinely used in children for anaesthesia. We evaluated the efficacy of the α2 adrenergic agonist, dexmedetomidine at two different doses as an adjuvant to bupivacaine in CB. Methods: This study was conducted on ninety children. Control group BD0 received 0.25% bupivacaine 1 ml/kg, whereas, the study groups BD1 and BD2 received 1 μg/kg and 2 μg/kg dexmedetomidine, respectively, with 0.25% bupivacaine 1 ml/kg as a single shot CB. Adequacy of the block, haemodynamic changes, duration of analgesia and side effects were compared. Analysis of Variance was used for between-group comparisons of numerical variables. Student's t-test and Mann–Whitney U-test were used for quantitative data. Results: The demography was comparable. Anal sphincter 5 min after administration of the CB was relaxed in 89.3%, 82.1% and 75% of cases in BD0, BD1 and BD2 groups, respectively. The sphincter was relaxed at the end of surgery in all the cases. Comparable haemodynamics was noted with significantly prolonged duration of analgesia in the groups BD1 (964.2 ± 309 min and BD2 (1152.6 ± 380.4 min compared to control (444.6 ± 179.4 min. While no complications were encountered in groups BD0 and BD1, bradycardia was observed in four cases of BD2 group with accompanied hypotension in one of them. Conclusion: Dexmedetomidine as an adjuvant to bupivacaine improves the quality of CB, provides good operating conditions and increases the duration of post-operative analgesia. We conclude that 1 μg/kg is as effective as 2 μg/kg of dexmedetomidine and with a better safety profile.

    Objective.To investigate the efficacy and safety of tetracaine hydrochloride in patient-controlled epidural analgesia(PCEA)after pulmonary lobectomy. Methods. Forty-three patients scheduled for elective pulmonary lobectomy under general anesthesia were randomly allocated into either tetracaine group(22 patients)or ropivacaine group(21 patients). In the tetracaine group,0.15% tetracaine was used for postoperative PCEA,while 0.3% ropivacaine was used in the ropiva-caine group. The duration of postoperative analgesia was 48 h. The PCEA included a bolus of 6 ml with a lockout time of 1 h. Postoperative pain score was measured by visual analogue scale(VAS). Forced expired volume at the 1st second(FEV1.0),forced vital capacity(FVC),FEV1.0/ FVC and peak expired flow(PEF)were measured preoperatively and daily after surgery. Hemodynamics were monitored and recorded before and after each administration of local anesthetics during the period of the study. Results. VAS scores in both groups decreased significantly after a bolus injection of local anesthetics. There was no significant difference between the two groups in VAS either before or after the administration of PCEA. On the 1st and 2nd days after the operation,pulmonary function was reduced in both groups. However,there were no significant differences between the percentage of the changes of FEV1.0,FEV1.0/FVC and PEF in the two groups. There were also no significant differences between the percentage of the changes of heart rate,mean arterial blood pressure and SpO2 after administration of local anesthetics. There was no significant difference in overall satisfaction with pain relief.Conclusions. The analgesic effect of 0.15% tetracaine is similar to that of 0.3% ropivacaine used in pa-tient-controlled epidural analgesia after thoracotomy. No serious side effects were observed.

    Full Text Available La meningitis bacteriana continúa siendo uno de los grandes problemas de la salud pública mundial. En particular, la infección por Neisseria meningitidis afecta tanto a países desarrollados como subdesarrollados, y se presenta en formas endémicas y epidémicas. La enfermedad meningocóccica se puede manifestar clínicamente no sólo como meningitis, sino con cuadros fulminantes de meningococcemia. La persistencia de N. meningitidis se debe al gran porcentaje de portadores y a la dinámica de transmisión de la bacteria. Aproximadamente 500 millones de personas en el mundo son portadoras de N. meningitidis en la nasofaringe. Los factores de transmisiblidad identificados han sido el tabaquismo activo o pasivo, la presencia de infecciones virales del tracto respiratorio superior, épocas de sequía, y el hacinamiento. Por lo anterior, se han descrito brotes de enfermedad meningocóccica en cuarteles militares, escuelas, cárceles y dormitorios. Algunos determinantes que permiten la invasión sistémica incluyen daños en la mucosa nasofaríngea de portadores, cepas virulentas con formación de cápsula, ausencia de anticuerpos bactericidas y deficiencias del sistema del complemento. El control de la enfermedad meningocóccica en circunstancias endémicas y epidémicas se logra por el tratamiento de casos con antibióticos adecuados (penicilina, ceftriaxona o cloranfenicol, la quimioprofilaxis de contactos cercanos (ciprofloxacina, rifampicina o ceftriaxona, y la vigilancia clínica de éstos. Sin embargo, es fundamental subrayar que la clave para el control efectivo de la enfermedad meningocóccica es la inmunoprofilaxis.

    Background There are several methods for postoperative analgesia for knee surgery.The commonly utilized method is multimodal analgesia based on continuous femoral nerve block.The aim of this study was to investigate the application of continuous adductor canal block for analgesia after total knee replacement and compare this method with continuous femoral nerve block.Methods Sixty patients scheduled for total knee replacement from June 2013 to March 2014 were randomly divided into a femoral group and an adductor group.Catheters were placed under the guidance of nerve stimulation in the femoral group and under the guidance of ultrasound in the adductor group.Operations were performed under combined spinal and epidural anesthesia.After the operations,0.2% ropivacaine was given at a speed of 5 ml/h through catheters in all patients.Visual analogue scale (VAS) pain scores at rest and while moving were noted at 4,24,and 48 hours after the operation,and quadriceps strength was also assessed at these time-points.Secondary parameters such as doses of complementary analgesics and side effects were also recorded.Results There were no significant differences between the groups in VAS pain scores at rest or while moving,at 4,24,or 48 hours after the operation (P >0.05).At these time-points,mean quadriceps strengths in the adductor group were 3.0 (2.75-3.0),3.0 (3.0-4.0),and 4.0 (3.0-4.0),respectively,all of which were significantly stronger than the corresponding means in the femoral group,which were 2.0 (2.0-3.0),2.0 (2.0-3.0),and 3.0 (2.0-4.0),respectively (P <0.05).There were no significant differences between the groups in doses of complementary analgesics or side effects (P >0.05).X-ray images of some patients showed that local anesthetic administered into the adductor canal could diffuse upward and reach the femoral triangle.Conclusions Continuous adductor canal block with 0.2% ropivacaine could be used effectively for analgesia after total knee replacement

  13. Inhibiting pain with pain--A basic neuromechanism of acupuncture analgesia

    (i) The structure and function of the meridian (chamd and collateral) described by ancient medical doctors may correspond to the blood circulation, nerve control and neurohumoral modulation of modern medicine. ( ii ) The needling, which can injure the tissue, is a noxious stimulation inducing pain. Acupuncture manipulation, such as lifting and thrusting, twisting and twirling, or electroacupuncturc (EA) with the sufferable biggest intensity for patients should be a stronger pain stimulation. The needling sensation of soreness, numbness, distension and heaviness is a deep pain.(iii) There is an intrinsic analgesic system in brain, which centers around the periventricular and periaqueductal grey matter, contains endorphins as possible mediators, goes through the descending inhibition system in medulla oblongata, and acts on the gating mechanism in spinal cord. It could be producing analgesia while the system is activated.(iv) NRM might be a supraspinal center modulating pain,and the R-S neurons could form a basic circuit of negative feedback modulating pain. The discovery of excitatory-inhibitory reversible R-S neurons may give a neurophysiological explanation for the double direction modulation of acupuncture at acupoint. (v) Non-noxious stimulation such as massage or stroking could excite type Ⅰ and Ⅱ afferent fibers, producing a weaker and transient analgesia through the spinal mechanism. When the acupoint is near the pain area, the afferent information from them could be converged on the same and neighboring spinal segments, the light acupuncture or low intensity of EA also has analgesic effects, showing acupoint specificity. But the acupoint specificity is not limited in a specialiy designated channel line, and it is closely related to the segment of innervation. (vi) While acupuncture manipulation of lifting and thrusting, twisting and twirling or a high intensity of EA is used, because the intensities of these stimulations exceed the threshold of afferent

    Full Text Available Background: The transverse abdominis plane (TAP block, a regional block provides effective analgesia after lower abdominal surgeries if used as part of multimodal analgesia. In this prospective, randomized double-blind study, we determined the efficacy of TAP block in patients undergoing cesarean section. Materials and Methods: Totally, 62 parturients undergoing cesarean section were randomized in a double-blind manner to receive either bilateral TAP block at the end of surgery with 20 ml of 0.25% bupivacaine or no TAP block, in addition to standard analgesic comprising 75 mg diclofenac 8 hourly and intravenous patient-controlled analgesia (PCA tramadol. Each patient was assessed at 0, 4, 8, 12, 24, 36, and 48 h after surgery by an independent observer for pain at rest and on movement using numeric rating scale of 0-10, time of 1 st demand for tramadol, total consumption of PCA tramadol, satisfaction with pain management and side effects. Results: Use of tramadol was reduced in patients given TAP block by 50% compared to patients given no block during 48 h after surgery (P < 0.001. Pain scores were lower both on rest and activity at each time point for 24 h in study group (P < 0.001, time of first analgesia was significantly longer, satisfaction was higher, and side effects were less in study group compared to control group. Conclusion: Transverse abdominis plane block was effective in providing analgesia with a substantial reduction in tramadol use during 48 h after cesarean section when used as adjunctive to standard analgesia.

    Full Text Available El Virus del Oeste del Nilo (VON es un Flavivirus que produce una encefalomielitis y puede afectar aves y mamíferos; los efectos varían desde poco notorios hasta la muerte, y en su difusión es importante la participación de especies animales como las aves donde es transmitido a través de mosquitos vectores. El VON se conoce de Uganda desde 1937 y está ampliamente distribuido en África, el oriente y la región sur y tropical de Eurasia. En el Hemisferio Occidental, el VON fue la primera causa de enfermedad en poblaciones de aves y humanos en Nueva York en 1999 y la epizootia ha continuado hasta ahora. La presencia del virus en Norteamérica junto con un número relativamente grande de aves migratorias susceptibles al agente, hacen de este virus de especial atención por su posible impacto sobre la fauna silvestre, los animales domésticos y el hombre en Sudamérica. La infección y mortalidad de aves normalmente precede a las epidemias en humanos y por lo tanto el monitoreo de aves es una herramienta preventiva efectiva que debe ser considerada seriamente.

  7. The effect of etoricoxib premedication on postoperative analgesia requirement in orthopedic and trauma patients

    International Nuclear Information System (INIS)

    We have hypothesized that etoricoxib premedication would reduce the need for additional opioids following orthopedic trauma surgery. A double blind, controlled study, conducted in King Fahd University Hospital, King Faisal University, Dammam, Kingdom of Saudi Arabia. After obtaining the approval of Research and Ethics Committee and written consent, 200 American Society of Anesthesiology grade I and II patients that underwent elective upper limb or lower limb fracture fixation surgeries during the period from August 2005 to October 2007 were studied. Patients were randomly premedicated using 120 mg of etoricoxib or placebo n=100, each. To alleviate postoperative pain, a patient controlled analgesia device was programmed to deliver one mg of morphine intravenously locked lockout time, 6 minutes. Visual analog scale and total postoperative morphine consumption over 24 hours and the adverse effects were recorded. One hundred patients in each group completed the study period. Etoricoxib premedication provides a statistically significant postoperative morphine sparing effect over 24 hours postoperatively. Total morphine consumption was 44.2 (8.2) in the placebo and 35.17 mg in the etoricoxib groups p<0.001. The incidence of nausea and vomiting requiring treatment was lower in the etoricoxib group. p=0.014. The postoperative blood loss was similar in both groups. Etoricoxib is a suitable premedication before traumatic orthopedic surgery as it enhanced postoperative analgesia and reduced the need for morphine. (author)

    We conducted a prospective study to assess how well parents ensured that their children received their prescribed analgesia following tonsillectomy. Our study was based on 69 cases of tonsillectomy that were carried out at our tertiary pediatric care center. Postoperatively, all patients were prescribed paracetamol (acetaminophen) on the basis of their weight; the standard pediatric dosage of this agent at the time of our study was 60 mg\\/kg\\/day. The parents were telephoned 2 weeks postoperatively to assess their compliance with this regimen. Of the original 69 patients who had been recruited, 66 completed the study-35 girls and 31 boys, aged 2 to 15 years (mean: 7.0; median 5.5). According to the parents, only 15 children (22.7%) received our recommended 60-mg\\/kg\\/day dosage and were thus determined to be fully compliant. Overall, parents reported a wide variation in the amount of drug administered, ranging from 12.5 to 111.0 mg\\/kg\\/day (mean: 44.8), indicating that parents often underdose their children. We recommend that more emphasis be placed on weight-directed, parent-provided analgesia during the post-tonsillectomy period.

    The aim of the present study was to investigate the effect of epidural analgesia combined with general anesthesia on hemodynamics. Thirty patients undergoing surgery for the treatment of cancer of the neck were studied. The patients were divided into two groups of those who received epidural analgesia combined with general anesthesia group (Group 1) and those with general anesthesia alone (Group 2). Blood pressure was not different between the groups. But heart rate and rate pressure products in Group 1 were significantly lower than those of Group 2. CVP in Group 1 increased significantly to 10.1 +/- 2.9 mmHg during surgery from 6.8 +/- 1.8 mmHg at the beginning of the surgery. There was no difference in intraoperative blood loss and the amount of fluid infused between the two groups. These results suggest that epidural anesthesia combined with general anesthesia is effective to stabilize hemodynamics during cervical surgery, but we have to be careful about using local anesthetics during long cervical procedures, because it increases CVP which might result from the depression of cardiac function.

  11. The cognitive modulation of pain: hypnosis- and placebo-induced analgesia.

    Nowadays, there is compelling evidence that there is a poor relationship between the incoming sensory input and the resulting pain sensation. Signals coming from the peripheral nervous system undergo a complex modulation by cognitive, affective, and motivational processes when they enter the central nervous system. Placebo- and hypnosis-induced analgesia form two extreme examples of how cognitive processes may influence the pain sensation. With the advent of modern brain imaging techniques, researchers have started to disentangle the brain mechanisms involved in these forms of cognitive modulation of pain. These studies have shown that the prefrontal and anterior cingulate cortices form important structures in a descending pathway that modulates incoming sensory input, likely via activation of the endogenous pain modulatory structures in the midbrain periaqueductal gray. Although little is known about the receptor systems involved in hypnosis-induced analgesia, studies of the placebo response suggest that the opiodergic and dopaminergic systems play an important role in the mediation of the placebo response.

    Full Text Available The use of transcutaneous electrical nerve stimulation (TENS as non-pharmacological therapeutic modality is increasing. The types of TENS used clinically are conventional TENS, acupuncture TENS and intense TENS. Their working is believed to be based on gate control theory of pain and activation of endogenous opioids. TENS has been used in anaesthesia for treatment of post-operative analgesia, post-operative nausea vomiting and labour analgesia. Evidence to support analgesic efficacy of TENS is ambiguous. A systematic search of literature on PubMed and Cochrane Library from July 2012 to January 2014 identified a total of eight clinical trials investigating post-operative analgesic effects of TENS including a total of 442 patients. Most of the studies have demonstrated clinically significant reduction in pain intensity and supplemental analgesic requirement. However, these trials vary in TENS parameters used that is, duration, intensity, frequency of stimulation and location of electrodes. Further studies with adequate sample size and good methodological design are warranted to establish general recommendation for use of TENS for post-operative pain.

    Objective. To compare the analgesic efficacy and adverse effects of patient-controlled analgesia (PCA) with tramadol and with morphine for postoperative middle or severe pain. Methods. Fifty-nine patients, scheduled for elective hysterectomy or hysteromyomectomy, were ran domly divided into Group T (tramadol-treated group) and Group M (morphine-treated group). The 2 drugs were administered intravenously via a patient-controlled analgesia device till 24 h postoperatively. Efficacy was assessed by comparing total pain relief (TOTPAR) and the sum of pain intensity difference (SPID) values over 24 h. Results. Statistically significant equivalence of tramadol and morphine was shown by TOTPAR values (15.9+4.4 and 16.4+3.5, respectively) and SPID values (9.2+4.7 and 9.0±2.0, respectively) (P>0.05). Tramadol caused fewer adverse events than morphine(16.7% and 26.7% of patients, respectively). Conclusion. The analgesic efficacy of PCA with tramadol and with morphine were equivalent in the treatment of postoperative pain, and tramadol can cause slighter gastrointestinal adverse effects.

    Full Text Available Abstract Background Intensivists must provide enough analgesia and sedation to ensure dying patients receive good palliative care. However, if it is perceived that too much is given, they risk prosecution for committing euthanasia. The goal of this study is to develop consensus guidelines on analgesia and sedation in dying intensive care unit patients that help distinguish palliative care from euthanasia. Methods Using the Delphi technique, panelists rated levels of agreement with statements describing how analgesics and sedatives should be given to dying ICU patients and how palliative care should be distinguished from euthanasia. Participants were drawn from 3 panels: 1 Canadian Academic Adult Intensive Care Fellowship program directors and Intensive Care division chiefs (N = 9; 2 Deputy chief provincial coroners (N = 5; 3 Validation panel of Intensivists attending the Canadian Critical Care Trials Group meeting (N = 12. Results After three Delphi rounds, consensus was achieved on 16 statements encompassing the role of palliative care in the intensive care unit, the management of pain and suffering, current areas of controversy, and ways of improving palliative care in the ICU. Conclusion Consensus guidelines were developed to guide the administration of analgesics and sedatives to dying ICU patients and to help distinguish palliative care from euthanasia.

    Full Text Available BACKGROUND AND OBJECTIVE: We compared the efficacy of intravenous (IV paracetamol versus dipyrone via patient-controlled analgesia (PCA for postoperative pain relief in children. METHODS: The study was composed of 120 children who had undergone elective tonsillectomy after receiving general anesthesia. Patients were divided into 3 groups according to the dosage of postoperative intravenous-patient-controlled analgesia: paracetamol, dipyrone, or placebo. Pain was evaluated using a 0- to 100-mm visual analog scale and 1- to 4-pain relief score at 30 min, 1, 2, 4, 6, 12, and 24 h postoperatively. Pethidine (0.25 mg kg-1 was administered intravenously to patients requiring rescue analgesia. Pethidine requirements were recorded during the first 24 h postoperatively, and treatment related adverse effects were noted. RESULTS: Postoperative visual analog scale scores were significantly lower with paracetamol group compared with placebo group at 6 h (p 0.05. Postoperative pethidine requirements were significantly lower with paracetamol and dipyrone groups compared with placebo group (62.5%, 68.4% vs 90%, p 0.05. CONCLUSIONS: Paracetamol and dipyrone have well tolerability profile and effective analgesic properties when administered IV-PCA for postoperative analgesia in children after tonsillectomy.

    To understand the mechanisms those are involved in the appearance of foetal heart rate decelerations (FHR) after the combined epidural analgesia in labour. Observational study done at University Hospital for 86-term singleton pregnant women with spontaneous labour. Serial bedside measurement of the main cardiac maternal parameters with USCOM technique; stroke volume (SV), heart rate (HR), cardiac output (CO) and total vascular resistances (TVR) inputting systolic and diastolic blood pressure before combined epidural analgesia and after 5', 10', 15' and 20 min. FHR was continuously recorded though cardiotocography before and after the procedure. Correlation between the appearance of foetal heart rate decelerations and the modification of maternal haemodynamic parameters. Fourteen out of 86 foetuses showed decelerations after the combined spino epidural procedure. No decelerations occurred in the women with low TVR (1200 dyne/s/cm(-5)). Soon after the epidural procedure, the absence of increase in SV and CO was observed in these women. No variations in systolic and diastolic blood pressure values were found. The level of TVR before combined epidural analgesia in labour may indicate the risk of FHR abnormalities after the procedure. Low TVR (<1000 dyne/s/cm(-5)) showed a reduced risk of FHR abnormalities. FHR decelerations seem to occur in women without the ability to upregulate SV and CO in response to the initial effects of analgesia. PMID:26333691

    Full Text Available This paper describes one of the three bridges which Hidrocivil, S. A., has built in Catalonia (northern Spain, over the river Ripoll. The other two bridges are very similar to this one, both in construction and design, and show only minor adjustments to the local topography. The contracting firm proposed several alterations in the prefabrication and constructional procedure, in relation to the initial project, and these changes were accepted. The main feature of these projects is the use of prestressed beams, built at the workshop in sections, and joined together by means of sixty 7 mm cables in each beam. As the shear forces are more acute at the joints, the end of each section has a kind of diaphragm, to provide a large contact area, and hence greater surface to transmit the shear forces. The methods of construction are also of interest. Briefly, they involve building the bridge piles, and use these to support a provisional structure with transversal movement. This provisional structure, in turn, served as platform for two bridge cranes, which lifted the girders to their final location. After the first span was completed, the deck was concreted and the auxiliary structure pushed forward to the next span, to repeat the same operations. This arrangement saved the use of provisional framework.En este trabajo se describe uno de los tres puentes que Hidrocivil, S.

    Full Text Available Background and Aims: Efforts to prolong analgesia with various intrathecal and oral adjuvants have been tried with varying success. The present study was aimed to explore and to compare the potential beneficial effects of prolongation of spinal analgesia with two different doses of oral clonidine. Materials and Methods: A randomized double-blind study was carried out among 60 (American Society of Anesthesiologists-I and II patients with aged range from 25 to 65 years undergoing lower abdominal surgery. They were divided randomly into three groups of 20 each. Group 1 patients were administered placebo whereas Group 2 and 3 received oral clonidine tablets (0.15 and 0.30 mg respectively 1-h prior to surgery. Subarachnoid block was administered as per standard protocol. Time to onset of analgesia at T-10, time to achieve maximum sensory level, dermatomal regression and time to rescue analgesia were observed. Side-effects such as hypotension, bradycardia, nausea and vomiting were noted. Statistical analysis was performed using ANOVA with post-hoc Students unpaired t-test and Chi-square test and value of P 0.05. Two segment regression was 78.3 ± 10.44 min, 150.2 ± 23.07 min and 149.3 ± 18.33 min in Groups 1-3 respectively. Time to rescue analgesia was significantly prolonged in Groups 2 and 3 compared with Group 1 (P < 0.05. Incidence of hypotension was higher in Group 2 (P < 0.05. Conclusion: Optimal dose of oral clonidine that produces clinically useful prolongation of spinal anesthesia using bupivacaine appears to be 0.15 mg when compared with 0.3 mg when overall efficacy is being compared.

    The effect of chronic and acute oral or intraperitoneal treatment with the antidepressant drugs, desipramine, amitriptyline, alaproclate and iprindole, upon pain thresholds in the tail flick, hot plate and shock titration tests of nociception in saline- and 5-MeODMT-treated rats was studied. Chronic desipramine treatment increased the pre-test tail flick latencies. In the saline-treated rats, chronic oral desipramine treatment increased tail flick latencies, whereas chronic oral amitriptyline treatment decreased tail flick latencies. In 5-MeODMT-treated rats, chronic oral desipramine treatment attenuated the effects of 5-MeODMT (1 mg/kg) in all three tests of nociception, whereas chronic amitriptyline caused a potentiation in the tail flick and hot plate tests. Chronic oral iprindole treatment attenuated 5-MeODMT-induced analgesia in the hot plate test. Chronic intraperitoneal desipramine treatment attenuated 5-MeODMT analgesia in the tail flick and shock titration tests. In a different chronic treatment experiment, oral desipramine treatment attenuated 5-MeODMT analgesia in the tail flick test and zimeldine did for both the tail flick and hot plate tests, whereas mianserin potentiated 5-MeODMT-induced analgesia in both the tail flick and hot plate tests. In the saline-treated rats, acute treatment with all four drugs, desipramine, amitriptyline, iprindole and alaproclate, elevated the shock thresholds, whereas in 5-MeODMT-treated rats, desipramine and amitriptyline elevated shock thresholds. Two main conclusions can be drawn: chronic desipramine caused a quite consistent attenuation of 5-MeODMT-induced analgesia and the effects of acute treatment differed strongly from that of the chronic treatment. The effects of chronic administration with these antidepressants were compared with other findings using different measures of behavioural and receptor function. PMID:3776549

    Full Text Available Multimodal analgesia refers to the practice of combining multiple analgesic drug classes or techniques to target different points along the pain pathway. The objective of this work was to evaluate clinically if ketoprofen associated or not with intravenous or epidural morphine provided adequate postoperative analgesia in bitches undergoing ovariosalpingohysterectomy (OSH. Forty healthy female dogs, weighing 10.7±6.0 kg, sedated with acepromazine (0.05mg kg –1.iv, induced with propofol (5 mg.kg-1. iv and maintained with isoflurane anesthesia, were distributed into four groups of 10 animals each. After stabilization of inhalation anesthesia, the bitches in Miv and CMiv groups received 0.2 mg.kg-1 of morphine intravenously diluted in 10ml of saline; whereas Mep and CMep groups received 0.1mg.kg-1 of epidural morphine. Thirty minutes after premedication, 2.0mg.kg-1.im of ketoprofen was administered in groups CMiv and CMep. Heart and respiratory rate, systolic blood pressure, and rectal temperature were measured. The degree of analgesia was assessed by a blind study in the following 6 hours after surgery, using a descriptive scale and a scale composed by physiologic and behavioral parameters. An statistical analysis was performed using the Tukey-Kramer test and nonparametric Kruskal-Wallis test, with statistical significance of 5%. There was no important difference between the four groups regarding postoperative analgesia, heart and respiratory rate, systolic blood pressure and rectal temperature. According to the results it can be concluded that the use of ketoprofen associated with intravenous or epidural morphine provided adequate and safe analgesia in the first six hours of postoperative in bitches undergoing ovariohysterectomy, suggesting that there was no analgesic potentiation when both agents were combined.

Patients were divided into two random groups as Group DR (desflurane + remifentanyl n=120 and Group DL (desflurane +Lumbar Epidural Analgesia n=120.The general anaesthesia in Group DR was performed through the use of desflurane and remifentanyl. Group DL was administered a general anaesthesia through a pre-operative epidural catheter insertion and an application of desflurane. Extubation, eye opening, head lift for 5 seconds, and the surgical durations of the patients as well as the postoperative side-effects were recorded. Modified Aldrete Scoring System was used to assess the recovery of the patients from anaesthesia. Results: According to the inter group comparison results between Group DR and Group DL, the duration of extubation, eye opening, head lift for 5 seconds and the average amount of elapsed time until the modified Aldrete Scoring reached 10 were found statistically and significantly shorter in Group DL than Group DR( respectively p=0.002, p<0.001, p<0.001, p<0.001.The duration of the first analgesic need was statistically and significantly longer in Group DL compared to Group DR (p<0.001. The postoperative patient satisfaction in Group DL was statistically and significantly higher than that in Group DR (p=0.010. Conclusion: The Epidural analgesia included in the general anaesthesia in lower abdominal surgery is considered by us to be the beneficial and efficient method of analgesia which leads to an earlier recovery of the patients without affecting the intraoperative hemodynamic stability and which boosts the patient satisfaction by providing a more efficient analgesia

    Aim:In light of the antinociceptive activity of the short-chain neurotoxin,cobrotoxin,and other acetylcholine antagonists,the antinociceptive activity and mechanisms of cobratoxin (CTX) ,a long-chain postsynaptic α-neurotoxin,was investigated in rodent pain models.Methods:CTX was administered intraperitoneally (30,45,68μg/kg) ,intra-cerebral ventricularly (4.5 μg/kg) or microinjected into periaqueductal gray (PAG;4.5 μg/kg).The antinociceptive action was tested using the hot.plate and acetic acid writhing tests in mice and rats.The involvement of the cholinergic system and opioid system in CTX-induced analgesia was examined by pretreatment of animals with atropine (0.5 mg/kg,im;or 10 mg/kg,ip) or naloxone (1 and 5 mg/kg,ip).The effect of CTX on motor activity was tested using the Animex test.Results:CTX exhibited a dose-dependent analgesic action in mice as determined by both the hot-plate and acetic acid writhing tests.The Deak effect of analgesia was seen 3 h after administration.In the mouse acetic acid writhing test,the intra-cerebral ventricular administration of CTX at 4.5μg/kg (1/12th of a systemic dose) produced marked analgesic effects.Microinjection of CTX (4.5μg/kg) into the PAG region did not elicit an analgesic action in rats in the hot-plate test.Atropine at 0.5 mg/kg (im) and naloxone at l and 5 mg/kg (ip) both failed to block the analgesic effects of CTX,but atropine at 1 0 mg/kg (ip) did antagonize the analgesia mediated bv CTX in the mouse acetic acid writhing test.Acetylsalicylic acid (300 mg/kg) did not enhance the analgesic effects of CTX.At the highest effective dose of 68μg/kg the neurotoxin did not change the spontaneous mobility of mice.Conclusion:CTX has analgesic effects.which are mediated in the central nervous system though not through the PAG.The central cholinergic system but not opioid system appears to be involved in the antinociceptive action of CTX.

    Endoscopic procedures of the gastrointestinal tract were successfully introduced into paediatric practice in the 1970s. Recent expansive development has become useful for improvement of both diagnosis and treatment in many children with gastrointestinal diseases. Most of these procedures are performed under procedural sedation (PSA) knowing anatomical, physiological and psychological differences and requiring good experience from the paediatrician and anaesthesiologist. These principles help to provide the procedure safely and minimise adverse events, which are greater the smaller the child is. Procedural sedation and analgesia in healthy children can be performed by a paediatrician, but children with congenital defects and serious coexisting diseases (ASA ≥ III) and also during the usage of anaesthetics (e.g. propofol), should be managed by an anaesthesiologist.

    Tattoos-ancient forms of permanent body ornamentation (body art) have today become popular fashion accessories worldwide. More than 50% of all tattoos are being done on women. In the recent years body tattooing in unconventional sites (e.g. lumbar and/or sacral area, lower abdomen, breast, and buttocks) has gained increasing popularity among young women (including in pregnancy). Although, the potential hazards of regional anesthesia in patients with lumbar tattoos remain controversial it may seem prudent to avoid a hollow needle insertion (possible tissue entrapment in its bore as the needle passes to the deeper structures) through a tattoo for neuraxial blocks. This author is not aware of any other review articles in English literature discussing implications, and complications of labor analgesia in parturients presenting with lumbar tattoos.

    Heart rate and heart-rate variability (HRV) were studied through a set of different methods in high (highs) and low hypnotizable subjects (lows) not receiving any deliberate hypnotic induction in basal conditions (simple relaxation) and during nociceptive-pressor stimulation with and without suggestions of analgesia. ANOVA did not reveal any difference between highs and lows for heart rate and for the HRV indexes extracted from the series of the interbeat intervals (RR) of the ECG in the frequency (spectral analysis) and time domain (standard deviation, Poincare plot) in both basal and stimulation conditions. Factors possibly accounting for the results and likely responsible for an underestimation of group differences are discussed. PMID:18569137

    Objective To assess the efficacy and safety of lomoxicam, one non-steroidal anti-inflammatory drug (NSAID) in patientcontrolled analgesia (PCA) in patients undergoing abdominal surgeries.Methods Thirty-nine patients scheduled for abdominal surgeries were randomly assigned to different PCA treatment groups using either lomoxicam or fentanyl postoperatively. Pain intensity difference (PID) and sum of pain intensity difference (SPID) were used to assess the analgesic efficacy of both drugs during a 24-hour period.Results The analgesic efficacy of lornoxicam is 1/66 of fentanyl, which was shown by SPID value of 3.250 and 3.058,respectively (P > 0.05). Lornoxicam caused fewer adverse events than fentanyl (33% vs. 68%, P < 0.05).Conclusion In clinic, we can use lomoxicam to treat postoperative pain effectively and with less adverse reactions compared with fentanyl.

    This proof of principle study examined the potential benefits of EEG neurofeedback for increasing responsiveness to self-hypnosis training for chronic pain management. The study comprised 20 individuals with multiple sclerosis (MS) who received 5 sessions of self-hypnosis training--1 face-to-face session and 4 prerecorded sessions. Participants were randomly assigned to have the prerecorded sessions preceded by either (a) EEG biofeedback (neurofeedback) training to increase left anterior theta power (NF-HYP) or (b) a relaxation control condition (RLX-HYP). Eighteen participants completed all treatment sessions and assessments. NF-HYP participants reported greater reductions in pain than RLX-HYP participants. The findings provide support for the potential treatment-enhancing effects of neurofeedback on hypnotic analgesia and also suggest that effective hypnosis treatment can be provided very efficiently.

    Endovenous laser ablation may be associated with significant pain when performed under standard local tumescent anesthesia. The purpose of this study was to investigate the efficacy of femoral and sciatic nerve blocks for analgesia during endovenous ablation in patients with lower extremity venous insufficiency. During a 28-month period, ultrasound-guided femoral or sciatic nerve blocks were performed to provide analgesia during endovenous laser ablation in 506 legs and 307 patients. The femoral block (n = 402) was performed at the level of the inguinal ligament, and the sciatic block at the posterior midthigh (n = 124), by injecting a diluted lidocaine solution under ultrasound guidance. After the blocks, endovenous laser ablations and other treatments (phlebectomy or foam sclerotherapy) were performed in the standard fashion. After the procedures, a visual analogue pain scale (1-10) was used for pain assessment. After the blocks, pain scores were 0 or 1 (no pain) in 240 legs, 2 or 3 (uncomfortable) in 225 legs, and 4 or 5 (annoying) in 41 legs. Patients never experienced any pain higher than score 5. The statistical analysis revealed no significant difference between the pain scores of the right leg versus the left leg (p = 0.321) and between the pain scores after the femoral versus sciatic block (p = 0.7). Ultrasound-guided femoral and sciatic nerve blocks may provide considerable reduction of pain during endovenous laser and other treatments, such as ambulatory phlebectomy and foam sclerotherapy. They may make these procedures more comfortable for the patient and easier for the operator.

    Full Text Available Background: Shoulder arthroplasty procedures are seldom performed on an ambulatory basis. Our objective was to examine postoperative analgesia, nausea and vomiting, patient satisfaction and complications of ambulatory shoulder arthroplasty performed using interscalene brachial plexus block (ISB. Materials and Methods: We prospectively examined 82 consecutive patients undergoing total and hemi-shoulder arthroplasty under ISB. Eighty-nine per cent (n=73 of patients received a continuous ISB; 11% (n=9 received a single-injection ISB. The blocks were performed using a nerve stimulator technique. Thirty to 40 mL of 0.5% ropivacaine with 1:400,000 epinephrine was injected perineurally after appropriate muscle twitches were elicited at a current of less than 0.5% mA. Data were collected in the preoperative holding area, intraoperatively and postoperatively including the postanesthesia care unit (PACU, at 24h and at seven days. Results: Mean postoperative pain scores at rest were 0.8 ± 2.3 in PACU (with movement, 0.9 ± 2.5, 2.5 ± 3.1 at 24h and 2.8 ± 2.1 at seven days. Mean postoperative nausea and vomiting (PONV scores were 0.2 ± 1.2 in the PACU and 0.4 ± 1.4 at 24h. Satisfaction scores were 4.8 ± 0.6 and 4.8 ± 0.7, respectively, at 24h and seven days. Minimal complications were noted postoperatively at 30 days. Conclusions: Regional anesthesia offers sufficient analgesia during the hospital stay for shoulder arthroplasty procedures while adhering to high patient comfort and satisfaction, with low complications.

There are several different clinical variations in the approaches used for achieving analgesia via TAP infiltration, and methods for identification of the TAP have evolved considerably since the landmark-guided technique was first described in 2001. There are many factors that impact the analgesic outcomes following TAP infiltration, and the various nuances of this technique have led to debate regarding procedural classification of TAP infiltration. Based on our current understanding of fascial and neuronal anatomy of the anterior abdominal wall, as well as available evidence from studies assessing local anesthetic spread and cutaneous sensory block following TAP infiltration, it is clear that TAP infiltration techniques are appropriately classified as field blocks. While the objective of peripheral nerve block and TAP infiltration are similar in that both approaches block sensory response in order to achieve analgesia, the technical components of the two procedures are different. Unlike peripheral nerve block, which involves identification or stimulation of a specific nerve or nerve plexus, followed by

    Opioids are widely used medicinally as analgesics and abused for hedonic effects, actions that are each complicated by substantial risks such as cardiorespiratory depression. These drugs mimic peptides such as β-endorphin, which has a key role in endogenous analgesia. The β-endorphin in the central nervous system originates from pro-opiomelanocortin (POMC) neurons in the arcuate nucleus and nucleus of the solitary tract (NTS). Relatively little is known about the NTSPOMC neurons but their position within the sensory nucleus of the vagus led us to test the hypothesis that they play a role in modulation of cardiorespiratory and nociceptive control. The NTSPOMC neurons were targeted using viral vectors in a POMC-Cre mouse line to express either opto-genetic (channelrhodopsin-2) or chemo-genetic (Pharmacologically Selective Actuator Modules). Opto-genetic activation of the NTSPOMC neurons in the working heart brainstem preparation (n = 21) evoked a reliable, titratable and time-locked respiratory inhibition (120% increase in inter-breath interval) with a bradycardia (125±26 beats per minute) and augmented respiratory sinus arrhythmia (58% increase). Chemo-genetic activation of NTSPOMC neurons in vivo was anti-nociceptive in the tail flick assay (latency increased by 126±65%, pmelanocortin receptor antagonist). The NTSPOMC neurons were found to project to key brainstem structures involved in cardiorespiratory control (nucleus ambiguus and ventral respiratory group) and endogenous analgesia (periaqueductal gray and midline raphe). Thus the NTSPOMC neurons may be capable of tuning behaviour by an opioidergic modulation of nociceptive, respiratory and cardiac control. PMID:27077912

Multivariable logistic regression demonstrated morphine NCA to be associated with greater odds of RRT activation (OR=3.29, 95% CI=1.35, 8.03, P=0.009 compared to fentanyl NCA. There were no statistically significant differences in pain scores after NCA initiation across NCA agents.Conclusion: NCA is safe in neonates and infants, with comparable efficacy demonstrated for the three agents used. The elevated incidence of RRT activation in patients receiving morphine suggests caution in its use and consideration of alternative agents in this population.

After taking informed consent, 120 patients of ASA Grade I and II were systematically randomised into four groups of 30 each. Patients were premedicated with midazolam 0.05 mg/kg intravenously and hydration with Ringer′s lactate solution 10ml/kg preoperatively in the holding room. Group I patients received Intrathecal injection of 15 mg bupivacaine with 1ml of normal saline and transdermal placebo patch. Group II patients received Intrathecal injection of 15 mg bupivacaine with 5 mcg of neostigmine and transdermal placebo patch. Group III patients received Intrathecal injection of 15 mg bupivacaine with 1ml of normal saline with transdermal nitroglycerine patch (5 mg/24 hours. Group IV patients received Intrathecal injection of 15 mg bupivacaine with 5mcg of neostigmine and transdermal nitroglycerine patch (5 mg/24 hours, applied on a non anaesthetised area after 20 minutes. Groups were demographically similar and did not differ in intraoperative characteristics like sensory block, motor block, haemodynamic parameters and SpO 2 . The mean duration of analgesia was 202.17 minutes, 407.20 minutes, 207.53 minutes and 581.63 minutes in control group (I, neostigmine group (II, nitroglycerine group (III and nitroglycerine neostigmine group (IV respectively (P< 0.01. To conclude, our results show that transdermal nitroglycerine itself does not show any analgesic potential but it enhances the analgesic potential of intrathecal neostigmine.

    Pain catastrophizing is associated with greater levels of pain. While many studies support the efficacy of hypnosis for pain, the effect on pain catastrophizing remains unclear. The present study evaluated the effect of hypnosis on pain catastrophizing using experimental heat stimulation. Twenty-two pain patients engaged in 3 conditions: baseline (no suggestion), hypnotic induction, and hypnotic induction plus analgesia suggestion. Participants with higher baseline pain showed a significant reduction in rumination following hypnotic induction plus analgesia suggestion and significant reductions in pain due to both the hypnotic induction alone and the hypnotic induction plus analgesia suggestion. The findings suggest that unpleasantness-focused hypnotic analgesia reduces pain via its effect on the rumination component of pain catastrophizing. PMID:27585727

    Full Text Available Introduction. Epidural analgesia has been a cornerstone of any ERAS program for open colorectal surgery. With the improvements in anesthetic and analgesic techniques as well as the introduction of the laparoscopy for colorectal resection, the role of epidural analgesia has been questioned. The aim of the review was to assess through a meta-analysis the impact of epidural analgesia compared to other analgesic techniques for colorectal laparoscopic surgery within an ERAS program. Methods. Literature research was performed on PubMed, Embase, and the Cochrane Library. All randomised clinical trials that reported data on hospital stay, postoperative complications, and readmissions rates within an ERAS program with and without an epidural analgesia after a colorectal laparoscopic resection were included. Results. Five randomised clinical trials were selected and a total of 168 patients submitted to epidural analgesia were compared to 163 patients treated by an alternative analgesic technique. Pooled data show a longer hospital stay in the epidural group with a mean difference of 1.07 (95% CI 0.06–2.08 without any significant differences in postoperative complications and readmissions rates. Conclusion. Epidural analgesia does not seem to offer any additional clinical benefits to patients undergoing laparoscopic colorectal surgery within an ERAS program.

    1988-01-01

    The effects of exposure to clinical magnetic resonance imaging (MRI) on analgesia induced by the mu opiate agonist, fentanyl, was examined in mice. During the dark period, adult male mice were exposed for 23.2 min to the time-varying (0.6 T/sec) magnetic field (TVMF) component of the MRI procedure. Following this exposure, the analgesic potency of fentanyl citrate (0.1 mg/kg) was determined at 5, 10, 15, and 30 min post-injection, using a thermal test stimulus (hot-plate 50 degrees C). Exposure to the magnetic-field gradients attenuated the fentanyl-induced analgesia in a manner comparable to that previously observed with morphine. These results indicate that the time-varying magnetic fields associated with MRI have significant inhibitory effects on the analgesic effects of specific mu-opiate-directed ligands.

    2015-09-01

    The fentanyl iontophoretic transdermal system (ITS) is a needle-free, patient-activated drug delivery system used for patient-controlled analgesia in adult hospitalized patients with postoperative pain. The system design has been updated to a separated system consisting of a Controller and a Drug Unit, and has had regulatory submissions in USA and Europe in 2014. Fentanyl ITS has been shown to be therapeutically equivalent to morphine intravenous (iv.) patient-controlled analgesia. One of the advantages of fentanyl ITS is that patients have better mobility as there is no need for an iv. pump, iv. lines and pole. The introduction of the updated fentanyl ITS will add a versatile tool to the postoperative pain management armamentarium.

    Full Text Available There are many circumstances in which the effectiveness of preventive measures depends to a large extent on the compliance of the patient in changing his or her behavior or lifestyle. It is shown how economic techniques can be used (i to describe the rationale of individuals and predict their behavior (Section 2; and (ii to assess preventive measures that, by requiring a change of conduct, imply "costs" to the individual due to a decline in the quality of life (Appendix. Cigarette smoking and coronary heart disease are used as an illustration. While the analysis of Section 2 uses graphical techniques, a simple textbook-type of lifetime utility model with a mathematical emphasis is used in the Appendix. It is also shown that techniques often used to assess health care programs such as the QALYs (Quality-Adjusted Life Years are inappropriate to the evaluation of preventive programs aiming at behavioral changes. Finally, topics that call for further research are indicated.A efetividade de muitas intervenções preventivas depende da capacidade do paciente em alterar seu comportamento ou estilo de vida. São intervenções nas quais o indivíduo exerce um papel ativo. Procurou-se mostrar como o instrumental econômico pode ser usado para: (i prever comportamentos e descrever sua lógica; e (ii avaliar medidas de prevenção que, por implicarem mudança de comportamento, geram "custos" em termos de queda na qualidade de vida (Apêndice.

    Full Text Available Effects of continuous low-dose epidural bupivacaine (0.05-0.1% infusion on the Doppler velocimetry for labor analgesia have been well documented. The aim of this study was to monitor the activity of the autonomic nervous system (ANS for women in labor based on Hilbert Huang transform (HHT, which performs signal processing for nonlinear systems, such as human cardiac systems. Thirteen pregnant women were included in the experimental group for labor analgesia. They received continuous epidural bupivacaine 0.075% infusion. The normal-to-normal intervals (NN-interval were downloaded from an ECG holter. Another 20 pregnant women in non-anesthesia labor (average gestation age was 38.6 weeks were included in the comparison group. In this study, HHT was used to decompose components of ECG signals, which reflect three different frequency bands of a person's heart rate spectrum (viz. high frequency (HF, low frequency (LF and very low frequency (VLF. It was found that the change of energy in subjects without anesthesia was more active than that with continuous epidural bupivacaine 0.075% infusion. The energy values of the experimental group (i.e., labor analgesia of HF and LF of ANS activities were significantly lower (P < 0.05 than the values of the comparison group (viz. labor without analgesia, but the trend of energy ratio of LF/HF was opposite. In conclusion, the sympathetic and parasympathetic components of ANS are all suppressed by continuous low-dose epidural bupivacaine 0.075% infusion, but parasympathetic power is suppressed more than sympathetic power.

    Full Text Available Background: Paravertebral block is a popular regional anesthetic technique used for perioperative analgesia in multiple surgical procedures. There are very few randomized trials of its use in laparoscopic cholecystectomy in medical literature. This study was aimed at assessing its efficacy and opioid-sparing potential in this surgery. Methods: Fifty patients were included in this prospective randomized study and allocated to two groups: Group A (25 patients receiving general anesthesia alone and Group B (25 patients receiving nerve-stimulator-guided bilateral thoracic Paravertebral Block (PVB at T6 level with 0.3 ml/kg of 0.25% bupivacaine prior to induction of general anesthesia. Intraoperative analgesia was supplemented with fentanyl (0.5 μg/kg based on hemodynamic and clinical parameters. Postoperatively, patients in both the groups received Patient-Controlled Analgesia (PCA morphine for the first 24 hours. The efficacy of PVB was assessed by comparing intraoperative fentanyl requirements, postoperative VAS scores at rest, and on coughing and PCA morphine consumption between the two groups. Results: Intraoperative supplemental fentanyl was significantly less in Group B compared to Group A (17.6 μg and 38.6 μg, respectively, P =0.001. PCA morphine requirement was significantly low in the PVB group at 2, 6, 12, and 24 hours postoperatively compared to that in Group A (4.4 mg vs 6.9 mg, 7.6 mg vs 14.2 mg, 11.6 mg vs 20.0 mg, 16.8 mg vs 27.2 mg, respectively; P <0.0001 at all intervals. Conclusion: Pre-induction PVB resulted in improved analgesia for 24 hours following laparoscopic cholecystectomy in this study, along with a significant reduction in perioperative opioid consumption and opioid-related side effects.
